ME: Ted Koppel's Son Died of Alcohol, Drug Overdose
The New York City medical examiner determined Friday the son of former ABC news man Ted Koppel died from a toxic mix of drugs and alcohol.

Andrew Koppel, 40, died inside a Washington Heights apartment on Memorial Day after going on a 12-hour drinking spree the day before with a friend, identified as 32-year-old Russell Wimberly. Cops were called to the Audubon Ave. residence at 1:30 a.m. after Wimberly found him unconscious.

Wimberly first told detectives he met Koppel the day before the drinking binge in Hell's Kitchen. However, cell phone records revealed the pair had known each other for more than a month.

Wimberly told investigators they ended up at the Washington Heights apartment of his friend Belinda Caban because Koppel was too intoxicated to go to another bar. Wimberly said when he tried to wake Koppel four hours later, he was dead and police were called.

An initial autopsy was inconclusive, however a spokeswoman for the Medical Examiner said Koppel suffered an "acute intoxication from alcohol, heroin, cocaine, and a generic form of Valium."
