SAN DIEGO — Twelve families have had their homes looted as they attended funerals for loved ones, and a ring of three suspects has been arrested, El Cajon police said Saturday.

The 12 bereaved families lost more than $100,000 in goods, officers said.

Two men and a woman were arrested, suspected of selecting targets by reading obituaries and finding houses they knew would be unoccupied.

El Cajon detectives arrested Herbert John Cruz, David Andrew Valenzuela, and Jennifer Lynn Alarcon last week for suspicion of burglary. The most-recent arrest was Wednesday, the department said as it announced the crime spree.

A task force of El Cajon and San Diego police, and San Diego County sheriff’s deputies searched residences and storage lockers connected to the suspects. Police said they found many items that were reported stolen.

Cruz remained jailed Saturday on a $550,000 bail, and Valenzuela was still jailed pending a $450,000 bail. Alarcon was not listed in the county jail population list, so it was not clear if she had made bail, or what that amount is.
