SoCal woman arrested in 2-year-old's drowning

[June 17, 2010]  NORCO, Calif. (AP) -- A California woman has been arrested on suspicion of drowning her 2-year-old son in a bathtub, authorities said Wednesday.

Brianne Luna, 22, of Norco, was arrested Tuesday night for investigation of murder, the Riverside County Sheriff's Department said.

She remained jailed Wednesday on $1 million bail. It wasn't immediately clear whether she had a lawyer.

Deputies were called to Luna's home at about 3:45 p.m. Tuesday after a family member called 911. They found firefighters trying to revive her son, Kaiden Johnston, who apparently had drowned in the tub. He was pronounced dead at a hospital.

Investigators said Luna refused to say what happened to her son.

"We believe this is a deliberate act and not a case of child neglect or child endangerment," said Deputy Melissa Nieburger.

There was no immediate word on a motive.
