Allegheny County authorities took 25-year-old McKeesport resident Quentin Ingram into custody Wednesday at an apartment in Versailles, near Pittsburgh.
Ingram is charged with criminal homicide and seven counts each of aggravated assault and reckless endangerment. He also faces a firearms charge.
Police were called to the Duquesne home shortly before midnight Dec. 17 after shots rang out in a basement where the party was being held. Eighteen-year-old Drew Henderson-Bracey was killed. Another adult and six youths were injured.
Authorities haven't commented on a possible motive for the shooting.
No listed telephone number for the arrested man can be found. It's unclear if he has an attorney.
