Authorities say Quezada is considered armed and dangerous.
Police believe Quezada killed Katherine Aguirre, 55, who was found with multiple gunshot wounds at 715 S. Merrill Street at 12:26 p.m. Wednesday. She was rushed to Corona Regional Medical Center, where she later died.
Quezada, 28, is the ex-boyfriend of Aguirre's 28-year-old daughter, Crystal Lopez. Police were searching Lopez, saying she was also in danger. Lopez had told friends on the phone and through Facebook that she was in hiding because she was afraid that Quezada was after her. On Thursday morning, Lopez walked into a police station and is now safe, police said. Lopez was not believed to be involved in the murder of her mother.
"Crystal came in this morning with some family members to let us know that she was safe, and she had been unharmed," said Corona Police Lt. Alan Lorton.
According to Kimberly Perez, a long-time family friend, Quezada had beat Lopez during an argument Wednesday morning, so Aguirre called police.
"I was there with her when she was talking to those cops, and then she came back to my house and she was scared. She said that she got a text message from his sister saying, 'Tell Crystal go run and hide because he's got a gun,'" Perez said.
Quezada's neighbor, who did not want to be identified, said on Wednesday, he came back to his house and discovered his vintage car had been vandalized. He then left in a fit of rage.
"He's always been a really cool, calm guy. I've never seen him in the state of mind as he was yesterday," she said.
Quezada later returned to the home looking for Lopez, but allegedly ended up shooting Aguirre. Friends say Lopez was taking her four sons to school at the time.
"I'm shocked, shocked, I know the brothers really well, and I was at work when I heard about it. I couldn't believe it," said Ray Aguilar, a family friend.
Quezada is believed to be driving a blue or gray 1982 Chevrolet pickup truck with California license plate number 2B29305.
Anyone who sees Quezada is urged to call 911. Police say do not attempt to approach or contact him. Anyone with information about the case is asked to call the Corona Police Department at (951) 736-2330, option 3.
