A 36-year-old woman was arrested on suspicion of attempted murder Tuesday after San Mateo County sheriff's deputies found her soaking wet with an infant at Poplar Beach in Half Moon Bay after allegedly walking into the ocean with the baby, sheriff's officials said.
Deputies responded around 3:10 p.m. to the beach off of Poplar Street on a report about a possible suicidal person there. They arrived and found Cupertino resident Chisato Chiyoda and the infant both soaking wet in 56-degree weather, according to the sheriff's office.
Chiyoda was seen acting strangely minutes earlier and had entered the water with the infant in what investigators later learned was an attempted murder-suicide. Both she and the baby were treated for hypothermia and were taken to a hospital for further evaluation, sheriff's officials said.
After detectives spoke with her and she was released from the hospital, Chiyoda was arrested on suspicion of attempted murder. The baby was also released from the hospital into the custody of Child Protective Services, according to the sheriff's office.
Anyone with information about the case is encouraged to contact Detective Velasquez at (650) 363-4062 or firstname.lastname@example.org.
