"What we do know is about nine o'clock last night an individual got out of a vehicle walked up to the house, fired multiple rounds into the house and unfortunately a 12 year old boy was struck in the upper body and is in critical, in fact grave condition and is on life support."
Dyer says up to a dozen people were in the house and someone inside, possibly a family member was the intended target.
"We are still trying to determine what the motive was for the shooting," Chief Dyer said. "We know he was an unintended target perhaps a mistaken identity and we don't have many leads as to who was responsible for this shooting."
Police say the home was known as a "gang house" and they fear the shooting could trigger violent retaliation. Dyer says a dozen detectives are on the case.
The wounded boy is a student of the Fresno Unified School District, but a school spokesperson declined to say which school the boy attended.
