July 26 (UPI) -- Los Angeles police have arrested a 26-year-old man they say shot four people to death, including his father and brother.
The Los Angeles Police Department said Gerry Dean Zaragoza was arrested Thursday afternoon, ending an hours-long manhunt through the San Fernando Valley.
"Investigators are working to determine a motive for these four homicides," the LAPD said.
Two officers with a joint LAPD-FBI task force restrained Zaragoza with a stun gun after he didn't comply with orders to put his hands up, the Los Angeles Times reported. Zaragoza, who police say was armed, received minor injuries in the scuffle.
Earlier, Zaragoza killed his father and brother and injured his mother, said LAPD Capt. William Hayes said. Officers said he shot a worker and a female acquaintance at a North Hollywood gas station. The woman later died.
Police said they're also investigating Zaragoza for possible involvement in an attempted ATM robbery and the shooting death of a man in Van Nuys.
Hayes said the first three victims were specifically targeted.
San Fernando Valley councilor Bob Blumfield thanked the police for ending a "horrible day of violence."
"This murder spree was beyond disturbing and I am incredibly grateful and relieved that the suspect is now in custody," he said.
Los Angeles Mayor Eric Garcetti said a crisis response team is giving support to those affected.
