FULLERTON — A 19-year-old man fell to the ground from the balcony of a third-floor apartment late Saturday, March 24, police said. He was taken to a hospital in serious condition.

The incident happened around 11 p.m. at the University House apartments at 555 N. Commonwealth Ave., a block from Cal State Fullerton.

Authorities do not suspect foul play but are looking at whether drugs or alcohol played a part in the fall, according to Fullerton Police Sgt. Dan Castillo. Others were believed to be present at the time, Castillo said.

The teen’s name was not released, and it was not known if he lived in the apartment.

Castillo said later Sunday that the teen is not a Cal State Fullerton student.

No further information about the incident was provided.
