A 3-year-old girl died in an apparent drowning after falling into the San Mateo Lagoon on Saturday afternoon, San Mateo police said Saturday night.
Emergency personnel responded to a 911 call at about 4:15 p.m. from a family in the 1500 block of Day Street, who reported their young daughter had wandered away from their home and was missing, San Mateo Police Sgt. Dave Norris said.
Police officers responded and searched for the child, who was quickly located unresponsive in a lagoon close to the family's apartment, Norris said.
Officers administered CPR until San Mateo fire personnel and American Medical Response paramedics arrived, who continued CPR but were unable to revive the girl.
She was pronounced dead at the scene.
The San Mateo Coroner's Office responded to take over the investigation, and authorities are calling the case a "tragic accidental death."
San Mateo Police and Fire Personnel are assisting the family in their time of grief.
