Jon Herrle, 55, pleaded guilty to manslaughter in the second degree in the death of the 38-year-old woman. Herrle gave his girlfriend a crushed opiod pill to get high, but told her it was cocaine.
When Herrle later found the woman unconscious on his couch, he fled the house and then called another person to "check on her," said Assistant District Attorney Nicholas Texido. The friend arrived, found the body and called 911.
Herrle is one of the very few people to have been charged locally for a direct connection to an overdose death.
Judge Sheila A. DiTullio agreed to cap Herrle's sentence at no more than 1 1/3 to 4 years in prison when he returns to court Jan. 18.
