III. No life-threatening injuries identified

B.
No injuries of anterior muscles of neck or laryngeal structures
C. No scalp soft tissue, skull, or brain injuries
D. No chest wall soft tissue injuries, rib fractures (other than a single rib fracture from CPR), vertebral column injuries, or visceral injuries
E. Incision and subcutaneous dissection of posterior and
lateral neck, shoulders, back, flanks, and buttocks
negative for occult trauma
VI. Toxicology (see attached report for full details; testing
performed on antemortem blood specimens collected 5/25/20 at
9:00 p.m. at HHC and on postmortem urine)
A. Blood drug and novel psychoactive substances screens:
1.
Fentanyl 11 ng/mL
2. Norfentanyl 5.6 ng/mL
3.
4-ANPP 0.65 ng/mL
4.
Methamphetamine 19 ng/mL
5. 11-Hydroxy Delta-9 THC 1.2 ng/mL;
Delta-9 Carboxy THC 42 ng/mL; Delta-9 THC 2.9 ng/mL
6. Cotinine positive
7. Caffeine positive
NECK: Layer by layer dissection of the anterior strap muscles of
the neck
discloses no areas of contusion or hemorrhage within
the musculature. The thyroid cartilage and hyoid bone are
intact. The larynx is lined by intact mucosa. The thyroid is
symmetric and red-brown, without cystic or nodular change. The
tongue is free of bite marks, hemorrhage, or other injuries.
The cervical spinal column is palpably stable and free of
hemorrhage.
CARDIOVASCULAR SYSTEM: The 540 g heart (upper limit of normal for
body length is 510 g; upper limit of normal for body weight is
521 g)1 is contained in an intact pericardial sac. The
epicardial surface is smooth, with modest fat investment. The
coronary arteries are present in a normal distribution, with a
right dominant pattern.
Cross sections of the vessels show
multifocal atherosclerosis, with 75% proximal and 75% mid
narrowing of the left anterior descending coronary artery; 75%
proximal narrowing of the 1st diagonal branch of the left
anterior descending coronary artery; 25% proximal narrowing of
the circumflex coronary artery; and 90% proximal narrowing of
the right coronary artery. The myocardium is homogeneous, redbrown, and firm. The valve leaflets are thin and mobile. The
walls of the left and right ventricles are 1.2 and 0.4 cm thick,
respectively. The endocardium is smooth and glistening. Both
ventricular cavities are mildly dilated. The minimally
atherosclerotic aorta gives rise to three intact and patent arch
vessels. The renal and mesenteric vessels are unremarkable.
An incision from the back of the head to the lower back,
extending onto both buttocks, is dissected subcutaneously to the
lateral aspects of the neck, the shoulders, and flanks.
No
areas of subcutaneous hemorrhage, soft tissue contusion, or
other occult injury are found in the posterior neck, right and
left lateral neck, shoulders, back, flanks, or buttocks.
MICROSCOPIC EXAMINATION:
HEART (3-5): Cross sections of left ventricular, right
ventricular, and interventricular septal
myocardium are examined and show the expected
microscopic architecture, with readily visible
boxcar nuclear changes in the septal and left
ventricular sections.
Cross sections of coronary
arteries, though not all ideally oriented,
confirm the gross impression of atherosclerotic
narrowing.
Fentanyl 11 ng/mL
Signs associated with fentanyl toxicity include severe respiratory depression, seizures, hypotension, coma and death. In fatalities from fentanyl, blood concentrations are variable and have been reported as low as 3 ng/mL.
