A man and woman were found dead Tuesday in Pico Rivera after a report of a shooting that authorities said appears to be a case of murder-suicide.

The bodies were found in the 9600 block of Kruse Road. The deaths appear to be a case of murder-suicide possibly involving a couple going through a divorce, according to a spokeswoman for the Los Angeles County Sheriff's Department.

The bodies were discovered in the home's kitchen by a relative at about 10 a.m. in a residential area just west of Pico Rivera Golf Course. During an argument, the 68-year-old man shot his 73-year-old wife the night before, then shot himself, according to sheriff's investigators.

"It's just something that you can't believe is going to happen to you," said the woman's aunt, Helen Chavez, after hearing about the slayings.

Investigators say the couple, identified as Antonio Sancho and wife Gloria Sancho, was scheduled to go to court Tuesday for a divorce proceeding. Relatives said Antonio Sancho didn't want the divorce and had refused to leave the home, which was up for sale.

"I knew she wasn't happy these last six months," Chavez said. "I don't know, she did apply for a divorce."

Neighbors said Antonio Sancho often argued with neighbors over parking issues and once tore down a neighbors fence with a hammer.

Investigators said Gloria Sancho's son, a man in his 50s who is severely disabled, was found inside another room unharmed and apparently unaware of the killings. He was being cared for at a hospital.

Correction: The couple's ages were incorrect in an earlier version of this report.
