I performed an autopsy on the body ofBROWN-SIMPSON, NICOLEat the DEPARTMENT OF CORONER Los Angeles, California on June 14, 1994 @0730 HOURS

From the anatomic findings and pertinent history, I ascribe the death to:MULTIPLE SHARP FORCE INJURIESDue To Or As a Consequence of _____________________________________________________________

Anatomical Summary:

I. Incised wound of neck:

A. Transection of left and right common carotid arteries.

B. Incisions, left and right internal jugular veins

C. Transection of thyrohyoid membrane, epiglottis, and hypopharynx.

D. Incision into cervical spine, C3.

II. Multiple stab wound of neck and scalp (total of seven).

III. Multiple injuries of hands, including incised wound, ring finger of right hand (defense wound).

IV. Scalp bruise, right parietal.


1. The body is described in the Standard Anatomical Position. Reference is to this position only.

2. Where necessary, injuries are numbered for reference. This is arbitrary and does not correspond to any order in which they may have been incurred. All the injuries are antemortem, unless otherwise specified.

3. The term "anatomic" is used as a specification to indicate correspondence with the description as set forth in the textbooks of Gross Anatomy. It denotes freedom from significant, visible or morbid alteration.


The body is that of a well-developed, well-nourished Caucasian female stated to be 35 years old. The body weighs 129 pounds and measures 65 inches from crown to sole. The hair on the scalp is brown. The irides are brown with the pupils fixed and dilated. The sclerae and conjunctive are unremarkable, without evidence of petechial hemorrhages on either. Both upper and lower teeth are natural, without evidence of injury to the cheeks, lips or gums.

There are no tattoos, deformities or amputations. Two linear surgical scars are found beneath each breast, transversely oriented and measuring 2 inches in length.

Rigor mortis is fixed at the time of autopsy examination (please see form 1).

The body appears to the examiner as stated above. Identification is by toe-tag and the autopsy is not material to identification. The body is not embalmed.

The head is normocephalic and there is external evidence of antemortem injury to be described below. Otherwise, the external auditory canals, eyes, nose and mouth are not remarkable. The neck shows sharp force injury to be described below, and the larynx is visible through the gaping wound.

No recent traumatic injuries are noted on the chest or abdomen; tan lines are seen on the lower abdomen (bathing suit). The genitalia are that of adult female with no gross evidence of injuries. Examination of the posterior surface at the trunk shows some excoriations compatible with postmortem injuries on the upper back, right side, on the medial aspect of the right scapula and on the lateral aspect of the right scapula (compatible with ant to insect bites). An abrasion above the left scapula measures 3/4 x 1/2 inch and is red-brown in color and appears antemortem. Otherwise, the lower back and remainder of the posterior aspect of the body shows no evidence or recent injuries.

Refer to available photographs and diagrams and the specific documentation of the autopsy protocol.


The decedent was wearing a short black dress, blood stained. Also, she was wearing a pair of black panties To the unaided eye examination there was no evidence of cut or tear.



The incised wound of the neck is gaping and exposes the larynx and cervical vertebral column. It measures 5 1/2 x 2 1/2 inches in length and is found at the level of the superior border of the larynx.

After approximation of the edges, it is seen to be diagonally oriented on the right side and transversely oriented from the midline to the left side. On the right side it is upwardly angulated toward the right earlobe and extends for 4 inches from the midline. On the left side it is transversely oriented and extends 2 1/2 inches to the anterior border of the left sternocleidomastoid muscle. The edges of the wound are smooth, with subcutaneous and intramuscular hemorrhage, fresh, dark red purple, is evident.

On the right side the upwardly angulated wound passes through the skin, the subcutaneous tissue, the platysma, passing under the ramus of the right mandible and upward as it passes through the strap muscles on the right, towards the digastric muscle on the right, and through the thyrohyoid membrane and ligament. Further dissection discloses that it passes posteriorly and transects the distal one-third of the epiglottis, the hypo-pharynx, and passes into the body of the 3rd cervical vertebra where it transversely oriented 3/4 inch incised wound is seen in the bone, extending it for a depth of 1/4 inch into the bone. The spinal canal and cord are not entered.

On the right side superiorly the wound passes towards the insertion of the sternocleidomastoid muscle, and then becomes more superficial and tapers as it terminates in the skin below the right earlobe.

On the left side the wound is transversely oriented and extends for 2 1/2 inches where the wound path intersects the stab wounds on the left side of the neck to be described below.

Dissection discloses that the right common carotid artery is transected with hemorrhage in the surrounding carotid sheath and there is a 1/4 incised wound or nick in the right internal jugular vein with surrounding soft tissue hemorrhage.

On the left side the left common carotid artery is transected with hemorrhage in the surrounding carotid sheath and the left internal jugular vein is subtotally transected with only a thin strand of tissue remaining posteriorly with surrounding soft tissue hemorrhage. The injuries on the left side of the neck intersect and the pathways of the stab wounds on the left side to be described below.

There is fresh hemorrhage and bruising noted along the entire incised wound path.

Depth of penetration is not given because the neck can be either flexed or extended, and the length of the wound is greater than the depth.

Opinion: This is a fatal incised wound or sharp force injury, associated with transection of the left and right carotid arteries and incisions of the left and right internal jugular veins with exsanguinating hemorrhage.


There are four stab wounds on the left side of the neck over the left sternocledomastoid muscle; they extend to 3 inches below the external auditory canal.

1. This stab wound overlaps that of the incised wound of the neck described above. The wound measures 5/8 inch in length, is vertically oriented, and has a squared-off end inferiorly approximately 1/32 inch and a pointed end superiorly. The minimal depth of the penetration, from left to right, is 1 1/2 to 2 inches where it intersects the incised wound. Penetration is through the skin, subcutaneous tissue and muscle, and injury to the internal jugular vein or common carotid artery cannot be excluded.

2. Stab wound of left side of neck: This is a 1/8 inch superficial slit-like incision into the skin and dermis; no squared-off or dull end is evident.

This is a superficial slit-like wound of the skin, non-fatal.

3. Stab wound on left side of neck: This is a diagonally oriented stab wound measuring 1/2 inch in length; there is a pointed end on the posterior aspect and a squared-off end anterior less than 1/32 inch in length. The edges are smooth, and dissection disposes a depth of penetration for 1 1/2 to 2 inches where the stab wound intersects that of the incised wound of the neck; the stab wounds are approximately 1 inch from the left lateral termination of the incised wound. Fresh hemorrhage is noted along the wound path which goes through the skin, subcutaneous tissue and muscle.

Opinion: This stab wound cannot be distinguished from injuries caused by the incised wound of the neck and may have injured the left common carotid artery and/or the left internal jugular vein.

4. Stab wound of the left side of neck: This is a diagonally oriented stab wound measuring 7/8 inch in length; on the posterior aspect there is a pointed end and on the anterior aspect a squared -off or dull end approximately 1/32 inch in width; otherwise the edges are smooth. Subsequent dissection discloses the wound path through the skin, subcutaneous tissue and muscle where it intersects the incised wound of the neck. Depth of penetration is 1 - 1/2 inches.

Opinion: This stab wound may have injured the left common carotid artery and/or the left internal jugular vein as described above.

5. Stab wound of scalp, left parietal: This diagonally oriented stab wound is located on the left parietal scalp, which is shaved postmortem for visualization. It measures 1/2 inch in length and no definite squared-off or dull end is evident, both ends appearing to be rounded. Depth of penetration is through the scalp, to the galea, approximately 3/8 - 1/2 inch. There is deep scalp hemorrhage and a subgaleal bruise, measuring 1 1/2 x 1 1/2 inches; there is no cutting wound or injury to the skull and there is no penetration into the cranium.

Opinion: This is a superficial stab wound or cutting wound of the scalp, non-fatal.

6. Stab wound or cutting wound of scalp: This is transversely oriented and is found in the right posterior parietal-occipital region. The transversely oriented wound measures 1 1/2 inches in length and has a pointed end to the left and a fork or split into the right. Depth of penetration is 3/8 - 1 1/2 inches with fresh deep scalp bruising.

Opinion: This is a non-fatal, stabbing or cutting wound of the scalp.

7. Stab wound or cutting wound of the scalp, right parietal-occipital: This is vertically oriented, measures 3/16 inch in length and involves the skin only. No squared-off or dull end is evident, both ends or aspects being pointed or tapered.

There is a small amount of deep scalp hemorrhage or bruising, no subgaleal hemorrhage.

Opinion: This is a non-fatal superficial stabbing or cutting wound of the scalp.

8. Blunt force injury to head: On the right side of the scalp, 4 inches above the right external auditory canal there is a scalp bruise; this is revealed after postmortem shaving of the scalp. It measures 1 x 1 inches and is red-violet or purple in color. The skin is smooth, non-abraded or lacerated. Subsequent autopsy discloses fresh deep scalp hemorrhage and fresh dark red-purple subgaleal hemorrhage or bruising measuring 2 x 1 1/4 inches. Inferiorly the bruise extends to the superficial right temporal muscle. There is no associated skull fracture.


Right hand: There is a 5/8 incised wound of the volar surface of the right index finger at the distal knuckle. This 5/8 inch incised wound is tangentially oriented or cut through the skin and dermis with the avulsed skin inferiorly indicating that the direction is from distal to proximal.

Further examination discloses that there is a split or forked end on the ulnar aspect and pointed end on the radial aspect. There is a small amount of dermal hemorrhage.

On the dorsal surface of the right hand, at the base of the ring finger, there is a 1/16 inch punctate abrasion.

Left hand: On the dorsal surface of the left hand, there is a punctate abrasion, red-brown in color at the base of the ring finger.

There is a 1/2 inch superficial incised skin cut, 1/2 inch in length, diagonally oriented, on the top of the left hand, midportion.


The body is opened with the usual Y-shaped thoracoabdominal incision revealing the abdominal wall adipose tissue to measure 1/4 - 3/8 inch in thickness.

Forms 16, 20, 20D, 20F, 20G, 20H, 22, 23, 24 and 29 were utilized during the performance of the autopsy.


Death is attributed to multiple sharp force injuries, including a deep incised wound of the neck and multiple stab wounds of the neck.

The sharp force injuries led to transection of the left and right common carotid arteries, and incisions of the left and right internal jugular vein causing fatal exsanguinating hemorrhage. The sharp force injury to the scalp were superficial, non-fatal.

Injuries present on the hands, including the incised wound of the right hand are compatible so-called defense wounds.
