Corona, Ca: Corona Shooting Suspect Armed, Dangerous - Police

Authorities are searching for a man in connection with the fatal shooting of a 55-year-old grandmother in Corona, and warning the public that her 28-year-old daughter also may be in danger.

Katherine Aguirre was shot and killed shortly after noon Wednesday, according to Corona police officials. The shooting happened at the victim's home in the 700 block of South Merrill Street, where Aguirre was found suffering from multiple gunshot wounds. She died at the hospital.

Aguirre's daughter -- Crystal Gene Lopez -- was last seen Wednesday morning and is not answering her cell phone, police said in an alert issued Wednesday afternoon. The mother of four young sons missed an appointment earlier in the day, family members told NBC4.

Carlos Martin Quezada, 28, of Corona, is wanted in connection with the slaying and is believed to be armed and dangerous, police said. Investigators believe Quezada may be dating Lopez, though a motive for the shooting has not been established.

"We believe he is out there looking for Crystal right now," said Lt. Alan Lorton, with Corona police.

Police are warning anyone who sees the suspect to call 911. He is believed to be driving a blue/gray 1982 Chevy pickup truck with California license plate 2B29305.

Anyone with information on the whereabouts of Lopez is asked to call the Corona Police Department at 951-739-2330, option 3.
