Serna was initially transported to Santa Clara Valley Medical Center for evaluation before being booked into county jail on suspicion of murder, officials from the Santa Clara County Sheriff’s Department confirmed to the Mercury.
Serna’s 8-month-old son was found dead inside a Sunnyvale apartment earlier in the day on Friday, but the cause of death is undetermined. The county medical examiner will conduct an autopsy on Monday, the Mercury News reports. An official cause of death will determine what charges will be filed against Serna.
Within minutes, police were notified of a woman hovering near the edge of the Mathilda Avenue overpass above Highway 101 and adjacent to her apartment complex.
“She was arrested as she apparently looked to leap,” Mercury News reporter Sean Webby wrote.
Serna remains in Santa Clara County Jail without bail. Anyone with information on the child’s death is asked to contact the Sunnyvale Department of Public Safety at (408) 730-7110. Those wishing to remain anonymous may contact SVTIP@tipnow.org.
The baby’s death, which remains under investigation, is Sunnyvale’s second homicide of 2011.
