SANTA ROSA (BCN) - A drug found in over-the-counter sleeping
pills was determined to exceed "potentially toxic" levels
in the body of a Stanford University graduate student found dead
in a Santa Rosa parking lot, officials said yesterday.
Sonoma County sheriff's Sgt. Mitch Mana reported that toxicology
tests on a sample taken from 23-year-old Mengyao "May"
Zhou showed the presence of diphenhydramine.
That chemical compound is the prime ingredient in the antihistamine
Benadryl, which is also a commonly used sleep aid that is available
without a doctor's prescription.
"No other common acidic, neutral or basic drugs detected,"
Mana reported. "No blood or urine ethyl alcohol detected."
The Sonoma County coroner's office was not elaborating on the
toxicology test results. An investigation continues into the death
of Zhou, found in the trunk of her car on Jan. 25 in a parking
lot at Santa Rosa Junior College. She was last seen leaving her
Stanford apartment on Jan. 20.
Officials have yet to determine formally Zhou's cause or manner
