BRISTOL, Pa. (AP) — A worker recently fired for absenteeism showed up outside a book warehouse in suburban Philadelphia on Friday, fatally shooting a veteran employee and a temp before being arrested, the company said.

The victims worked for Simon & Schuster's distribution center in Bristol, said company spokesman Adam Rothberg.

The shooting happened around 3:30 p.m. during a shift change at the warehouse, which employs 125 full-time workers and is about 20 miles north of Philadelphia, Rothberg said.

Reginald Woodson, 52, of Willingboro, N.J., was shot in his car. He had worked at the warehouse for 20 years as a forklift operator and was a shop steward. The other victim, Angel Gonzales, was a temporary worker.

Witnesses told the Bucks County Courier Times that the man taken into custody by police had threatened violence against some of his co-workers in the past.

Calls to Bristol police and the Bucks County prosecutor's office were not returned.

Rothberg said the man who was arrested began working at the plant in 2002 and was fired in April for absenteeism. He declined to release the name of the suspect and would not elaborate on the shooting.
