A jury found Israel James guilty on all charges for sexually abusing a 17-year old girl while she was asleep on Thursday.
Prosecutors say the assault took place September of last year, inside the victim's bedroom in Upper Darby.
When officers responded to a 911 call, they found the victim outside in the street crying. She stated she was assaulted by James, who is a relative.
The victim told police she woke up to find James laying beside her in his underwear, touching her inapropriately. She told police that when she tried to run away he grabbed her and tried to prevent her from leaving the room, but she was able to break free and get away.
The teen was able to identify James for police and he was arrested and charged.
No sentencing date was set.
