Police: Arizona mom drowned twin boys, tried to kill third child

AVONDALE, Ariz. --Police say a 22-year-old woman confessed to purposely drowning her twin sons in a bathtub Sunday, reports CBS affiliate KPHO.

Officers arrested Mireya Alejandra Lopez, of Avondale, Ariz., after her 2-year-old boys were rushed to different hospitals.

The boys' grandmother called 911 at about noon, said Avondale Police Sgt. Brandon Busse. When first responders arrived at the home, the children were on a bed.

The working theory was the boys drowned in a bathtub, Avondale Fire Chief Ron Deadman said.

Lopez also reportedly confessed to attempting to drown a third child, who managed to survive uninjured.

The twins' father, Sam Avitia, told police he had joint custody of the boys and was scheduled to get them Friday. Avitia also said Lopez suffered from depression and anxiety, but has never threatened anyone and never shown any violent tendencies.

Lopez was booked on two counts of homicide and one count of attempted homicide.
