Party-goers spin violent tale about DJ

Apparently an argument led to this. Four people were injured. One seriously. Here's the story:

WEST COVINA - The DJ at a house party was arrested early Sunday after he allegedly stabbed two people and hit two others with his car, authorities said.

Luis Perez, 23, of Baldwin Park was arrested shortly after the incident and was booked on suspicion of attempted murder, West Covina police Lt. Marcos Plebani said.

The alleged attack occurred about 2 a.m. at a house in the 1600 block of West Louisa Avenue, he said.

"He slashed one person in the back yard, then stabbed another person multiple times in the front yard," Plebani said.

A 26-year-old man was hospitalized with three stab wounds to his stomach and lower chest, said West Covina Fire Department Capt. Jim Rudroff.

The injuries were initially believed to be life threatening, however the wounded man was expected to survive after undergoing surgery, police and fire officials said. Another man suffered a superficial stab wound but did not seek treatment from fire officials.
