I'm Nicole Parton in Washington. Two young parents are facing serious murder charges following the tragic death of their newborn baby.

Authorities reveal that while their infant was critically ill in the hospital, the mother recorded a TikTok dance to a lively song right in front of her dying child.

On March 12, prosecutors in Pierce County charged 19-year-old Alyssa Jade Vanderbeck and 21-year-old

Mark Anthony Klamour with second-degree murder, with Klamour also facing charges of

homicide by abuse.

This comes just days after the couple's seven-week-old son, referred to in court documents as

NC, passed away due to what was described as an abusive head trauma.

The baby was admitted to Mary Bridge Children's Hospital in Tacoma on

March 4 in critical condition, and he died on March 9. According to a probable cause affidavit,

medical examiners revealed that the child had suffered from multiple severe injuries, including

hemorrhages and a brain injury, which were deemed consistent with

abusive head trauma. An autopsy indicated that the likely cause of death was homicide resulting

from these injuries. During interviews with the investigators from the Lakewood Police Department,

clamor admitted to handling the baby roughly,

acknowledging that he had jerked the child in a way that he recognized was too hard.

It was discovered that the couple delayed calling 911 for about an hour after noticing the baby

was in distress. Clammer contacted emergency services stating that his son was not breathing. He explained

to investigators that after the baby became fussy, he picked him up and, quote, jerked him,

causing the baby's head to move back forcefully. Benderbeck recounted that she was awakened to

Klamour placing the baby down for a nap.

And after a shower, they heard the baby making odd noises and found him unresponsive.
