Tiny baby Nakoa lay in a hospital bed, eyes closed, with tubes inserted to assist his breathing as his life gradually faded away.

Just steps away, his mother, 19-year-old Alyssa Jade Vanderbeck, seemed indifferent to her son’s critical condition as she showcased her appearance on TikTok.

In a now-deleted video, acquired by the Daily Mail, the young mother is seen ‘dancing slowly in the bathroom of [Nakoa’s] hospital room to what can be described as upbeat music,’ according to the charging documents.

In the seven weeks leading up to this, Vanderbeck attempted to present herself as a devoted mother, deeply affected by her son’s dire situation.

She shared numerous TikTok videos, showing herself lovingly holding her newborn and celebrating milestones like his first night sleeping through.

Then, on March 9, she posted a poignant clip of the tiny infant in his hospital bed, as she held him, marking a somber moment as his life ebbed away.

‘Having no one who understands what I’m going through or how I’m grieving is harder than ever. Losing so much all in one day,’ she wrote.

But away from her phone camera, the reality was much different – and she is now behind bars facing decades in jail, accused of causing Nakoa’s horrific death.

Vanderbeck and her boyfriend Mark Anthony Labaco Clamor, 21, are charged with second-degree murder after Nakoa died on March 9. 

They have both pleaded not guilty. 

The baby’s autopsy found he suffered ‘subdural hemorrhages, anoxic brain injury, and retinal hemorrhages’ and died from ‘homicide due to abusive head trauma.’

Medical examiners also found ‘possible healing rib fractures’ that allegedly pointed to earlier abuse.

Nakoa was first rushed to Mary Bridge Children’s Hospital in Tacoma, Washington, on March 4 in critical condition.

Clamor admitted to Lakewood Police Department detectives that he picked up Nakoa when the boy was being ‘fussy’ and jerked him ‘in a manner that he realized was rough,’ police alleged.

The father ‘saw the child’s head “jerk back pretty hard” before trying to catch the child’s head and pull the infant to his chest.’

Vanderbeck told police the couple then took a shower together as their baby slept, and when they returned he was making ‘grunting noises’.

‘She and Clamor tried to rouse [Nakoa] by stimulating him physically, which included shaking him in a panic,’ according to the charging affidavit.

Instead of immediately calling 911, Vanderbeck filmed several videos of her child ‘in serious distress’ and sent them to friends and family asking for help, phone data showed.

Screengrabs of the videos obtained by the Daily Mail showed the infant in a car seat looking distressed in one, and unresponsive in another.

The affidavit described them as showing Nakoa ‘with labored breathing which included posturing and grunting’ and in another he ‘appeared to have stopped breathing.’

The couple allegedly waited an hour after Nakoa began struggling before finally calling 911, telling the operator their son wasn’t breathing.

Vanderbeck messaged her close friend Macy just before midnight, claiming she had no idea how her baby was in such bad shape.

‘He might not make it… not sure so far,’ she wrote in the Facebook message.

‘They said his oxygen may have cut off… dude I have no clue what’s going on. So many wires. So many doctors. Now [Child Protective Services].

‘I want him in my arms and I want answers.’

Vanderbeck told Macy that doctors believed Nakoa ‘hit his head,’ though test results were not back yet.

‘But he hasn’t ever hit his head or fallen off of anything. He was fine all morning. Then this happened,’ she wrote, sending two videos of Nakoa in distress.

Macy asked if Vanderbeck ever left her son alone with Clamor, and she insisted she was ‘always home’ and was ‘on the couch all day next to them.’

‘I napped for two hours, woke up and he was still fine, then we showered and all of a sudden he’s acting weird,’ she wrote.

‘He was in his bouncer in the bathroom, never left our side. I keep coming up with theories but they tell me it’s all not possible.

‘How can’t they tell I’m truly confused on what happened to my son, Mark’s been bawling.’

Vanderbeck complained that a doctor called her ‘nosy’ for asking questions and that she was ‘losing [her] s**t.’ She then casually admitted Nakoa was going to die.

‘He is okay, he’s going to pass but not yet,’ she wrote.

Vanderbeck then complained that someone, likely her older sister Makayla, was ‘disrupting our grief’ by blaming Clamor.

‘Which is putting Mark in a horrible state of mind making it hard for us to support each other,’ she wrote.

Vanderbeck claimed Makayla’s boyfriend called Clamor a ‘murderer and a coward’ and she called police claiming they were ‘lying about a crime he didn’t do.’

‘She won’t listen to the fact that over 19 doctors and like 5 police officers investigated us and deemed us safe parents,’ she wrote.

This was less than a week before Clamor was charged with murder.

Vanderbeck claimed in the texts that doctors told Clamor that ‘it’s very obvious it was accidental and he is a grieving hurt parent.’

Macy asked if Nakoa was suffering from ‘shaken baby syndrome’ and Vanderbeck put forward her theory of why her son was at death’s door.

‘Yes it was but he had a brain bleed from his birth and it came back from the shake so he was like easier prone to getting a brain bleed because he was a vacuum delivery,’ she claimed.

A vacuum delivery involves putting a suction cup on the baby’s head to assist in getting the child out, but risks scalp injuries and bruising.

Rare complications include brain bleeds, which can be serious if enough pressure builds up on the brain, according to the Cleveland Clinic.

Shaken baby syndrome, which Vanderbeck appeared to admit to in her messages, is a serious condition caused by a baby being jerked around or shaken and many parents have been jailed for injuring or killing their babies from it.

Macy wrote on Facebook after Vanderbeck’s arrest that she was ‘so f**king disgusted and disappointed.’

‘She better be glad my baby was always happy and unharmed when we picked him up. I’ve given her money numerous times for that baby and now I’m sure she never even used it for him,’ she wrote.

‘Had the nerve to be messaging me lies to establish a timeline and alibi for herself all while her baby was fighting for his life.’

Detectives arrived at the hospital on March 5 to investigate Nakoa’s injuries as possible child abuse, but the couple were nowhere to be found.

When they finally returned, police ‘found their demeanor to be unusual considering the gravity of the suspected offense and the condition their child was in.’

The officers then interviewed the parents separately, but let them go pending a full investigation.

‘Throughout the interview, Clamor was emotional, tearful at times, and appeared exhausted. He expressed ongoing stress relating to finances, housing, unemployment, and exhaustion from childcare,’ the affidavit stated.

Neither of the couple had a job since Clamor was let go in December.

Numerous family and friends claimed they gave Vanderbeck money after she begged for funds to look after her baby.

‘I went to high school with you and even gave you money for food, diapers and gas!’ her friend Aaliyah Moreno wrote.

‘This is truly disgusting and I’m so sick to my stomach that you would even THINK to lay a hand on your OWN CHILD. My heart breaks for Nakoa. 

‘You reached out to me because you had postpartum depression I felt bad for you and even tried to help you! But now that your true colors have shown I am so disgusted by you.’

Another friend, Mihaela Mircea, a new mother herself, shared screenshots of Vanderbeck asking her to buy her formula because Clamor’s unemployment was about to run out.

‘I’m getting so stressed out I just wanna keep our baby safe,’ one of the messages read.

Mircea wrote when she shared the messages online she was furious the couple allegedly killed their baby because they just asked for money and didn’t get help.

‘I cleaned their whole apartment at 37 weeks pregnant and gave money. They had support. They could have reached out but they didn’t,’ she wrote.

‘I helped her out with a lot of money too. Like in the hundreds of dollars.’

Other friends shared similar sentiments.

Makayla, 23, said it was obvious her sister was not ready to be a mother, but her family was shocked by the murder charges.

‘God I love you so much Alyssa but what the actual f**k,’ she wrote.

‘I moved out at the same age as her and have had a job and roof over my head this whole time. They clearly made poor choices.’

‘She was told multiple times by family to get an abortion because she isn’t ready yet. Although we never ever thought they’d abuse him. 

‘There were signs of mental and financial struggles but I would never think my sister would hurt her baby. I’ve never met mark so I have no clue. Them being together was a mess from the start.

‘I no longer have a nephew. I just don’t understand. She is smarter than this.’

Vanderbeck faced court on March 12 where she cried as she was remanded into custody on a $1 million bail that she couldn’t pay.

The couple pleaded not guilty and will face court again on April 8.
