The Latest: Child welfare workers went to California home 4 times before deaths of 2 kids

The latest on the discovery of two dead children in a California storage facility (all times local):

2:15 p.m.

Child welfare workers visited a Northern California woman suspected in the deaths of two children four times in the past year on allegations of neglect.

Elliot Robinson, head of the Monterey County Department of Social Services, tells the San Francisco Chronicle in a story Wednesday that investigators couldn't find a big enough risk to the youngsters in her care to remove them from her apartment in Salinas.

The investigation led to a 9-year-old girl found Friday suffering from neglect and abuse 300 miles away in Quincy, where the woman had recently moved. Later, investigators found two small children dead in a storage unit 150 miles away in Redding.

The woman and a 17-year-old boy were arrested on abuse allegations related to the 9-year-old. They have not been charged in the deaths.
