Children Orphaned After Father, Mother Killed in Separate Incidents

Tragedy struck twice in less than one month for four children who lost their mother last week in a hiking accident.

Adrian Cardona, the father of the woman's four children, was killed Monday night after a dispute with a woman at a bar in San Bernardino, police said. Police were investigating the cause of the shooting.

Police said they could not release a description of the shooter and had not made any arrests.

The children's mother, Anna L. Santana, 34, died July 6 when ice and rocks fell inside of ice caves in Washington state.

The accident happened when Santana, from Moreno Valley, went on a hiking excursion on a remote mountainside in Washington. Three people were also injured during that accident.

Investigators said they were following up on leads in the shooting of Cardona. Police found a handgun at the scene of the shooting, but said the caliber does not match bullet that killed Cardona.

A GoFundMe account has been set up to help the family of Anna Santana: http://www.gofundme.com/yzsf4s.
