Jeffrey Charles William Michael Conaway (October 5, 1950 – May 27, 2011) was an American actor, and singer known for playing Kenickie in the movie Grease, and for his roles in two American television series, Taxi and Babylon 5. Conaway was also featured in the first and second seasons of the reality television series Celebrity Rehab with Dr. Drew.
On May 11, 2011, Conaway was found unconscious from what was initially described as an overdose of substances believed to be pain medication and was taken to Encino-Tarzana Regional Medical Center in Encino, California, where he was listed in critical condition. After initial reports, Drew Pinsky, who had treated Conaway for substance abuse, said the actor was suffering not from a drug overdose but rather from pneumonia with sepsis, for which he was placed into an induced coma. Though his pneumonia was not directly a result of drug usage, drug usage hampered Conaway's ability to recognize how severely ill he was and to seek treatment for pneumonia until it was too late.
On May 26, 2011, Conaway's family took him off life support after doctors decided there was nothing they could do to revive him. Conaway died the following morning at the age of 60. Conaway's doctor attributed his death to his addiction, stating, "What happens is, like with most opiate addicts, eventually they take a little too much ... and they aspirate, so what's in their mouth gets into their lungs ... That's what happened with Jeff."
An autopsy performed on Conaway revealed that the actor died of various causes including pneumonia and encephalopathy attributable to drug overdoses.
