A Washington state couple, Mark Anthony Labaco Clamor, 21, and Alyssa Jade Vanderbeck, 19, are facing second-degree murder charges after their 7-week-old son died from injuries consistent with abusive head trauma. The case has drawn national attention not only for the alleged abuse, but also for reports that the mother filmed a TikTok video in the hospital while her son was dying.

Why it matters

This case highlights the devastating consequences of Shaken Baby Syndrome, also known as Abusive Head Trauma, which is a leading cause of traumatic brain injury in infants. It also raises questions about the impact of social media on individuals' behavior during times of crisis.

The details

According to court documents, Clamor called 911 on March 4th, reporting that his son was not breathing. Investigators allege the couple waited approximately one hour before seeking medical help. Upon arrival at the hospital, doctors found the infant suffering from severe injuries including subdural hemorrhages, anoxic brain injury, retinal hemorrhages, and possible healing rib fractures. Authorities noted the parents' 'unusual demeanor' when they arrived at the hospital to investigate. Clamor allegedly admitted to police that he had handled the baby 'roughly' after the infant became 'fussy,' stating the baby's head 'jolted back pretty hard.' Vanderbeck reportedly told investigators she observed Clamor attempting to revive their son and then filmed videos of the distressed infant, sending them to family and friends seeking advice.

  • On March 4th, Clamor called 911 reporting that his son was not breathing.
  • On March 8th, Vanderbeck posted a TikTok video of herself 'slowly dancing' in the bathroom of her son's hospital room.
  • On March 9th, the couple's 7-week-old son died from his injuries.
