On January 16, Sandoval’s mother, Elaina Rose Welch, 32, called police claiming her son was dead. Welch exited the home with a shotgun in hand, but was detained. When San Diego County Sheriff’s Deputies entered the home they found the body of Welch’s boyfriend, 32-year-old Julio Ricardo Monggiotti. He had been shot to death, according San Diego ABC News affiliate 10 News.

The next day, Sandoval’s body was found in a freezer in the garage under some frozen food.

Welch was charged with two counts of murder. Then, on January 22, all charges were dropped and she was released from jail.
