LEBANON – Police are investigating drug overdoses by two teen-agers who attended the same party.

Investigators from the York County Sheriff’s Department believe the overdoses are linked to a party that occurred Wednesday night at a home in Lebanon, the department said Thursday.

The first overdose was reported at 8:23 p.m. and the second was reported at 10:25 p.m., both after the teens returned home.

The first involved a 15-year-old girl who became unresponsive and only partly alert, police said. The second involved a 17-year-old boy. Both were taken to a hospital in Sanford.

Police believe the girl overdosed on either Ecstasy or liquid morphine, and that the boy may have taken liquid morphine with another prescription drug, along with alcohol.
