Emergency Response to Lakewood Residence Reveals Critical Infant Injuries

A tragic investigation began in Lakewood earlier this month when emergency services received a 911 call regarding an infant who had stopped breathing. On March 4, Mark Anthony Labaco Clamor, 21, and Alyssa Jade Vanderbeck, 19, alerted authorities to their two month old son’s condition. First responders transported the child to the Pediatric Intensive Care Unit at Mary Bridge Children’s Hospital in Tacoma. Despite intensive medical intervention, the infant remained in critical condition for five days before succumbing to his injuries on March 9.

Medical Examination Uncovers Patterns of Physical Abuse

Following the infant's death, forensic specialists and medical examiners conducted a detailed review of the physical evidence. The examination revealed significant brain hemorrhaging, extensive retinal hemorrhages, and indicators of possible rib fractures. Medical professionals stated that these injuries are hallmark signs of abusive head trauma, often resulting from violent shaking or rough handling. The clinical findings contradicted the initial suggestions that the child’s condition was the result of a natural medical event or a typical household accident.

Suspect Statements Detail Violent Movement and Delayed Reporting

During subsequent interviews with investigators, Clamor reportedly admitted to rocking the infant with a violent and jerking motion after the child became fussy. Court documents indicate he observed the infant’s head jerk back with significant force during the incident. Vanderbeck told authorities she had been napping and initially believed the child might be suffering from gas or a seizure. Critically, investigators determined that approximately one hour passed between the onset of the infant's distress and the couple's decision to contact emergency services.
