In a harrowing case that has gripped Texas, a mother and her boyfriend now face capital murder charges following the tragic death of her 3-year-old son. The young boy, who had been fighting for his life for two months after suffering severe injuries, was taken off life support on Sunday.

Authorities have charged Chelsea Rene Berg and Christopher Thomas Alexander with capital murder of a person under 10 years old. These charges come in the aftermath of the grievous injuries sustained by the toddler, Dawson Cain Zamora, as reported by KVII.

The heart-wrenching news of Dawson’s death was shared by his father on social media. “My son Dawson has passed away,” Dahrian Zamora expressed, as reported by KDFW. “He held on to spend one last birthday with me and refused to go until then.”

The initial arrests of Berg and Alexander took place in October, following Dawson’s hospitalization. The child arrived at the hospital with critical brain trauma, a brain bleed, multiple bruises in various stages of healing, chest and abdominal wounds, and evidence of anal trauma. This distressing situation was previously detailed by CrimeOnline.

Berg and Alexander were initially arrested in October after the toddler, Dawson Cain Zamora, was brought to a hospital with severe brain trauma, including a brain bleed, bruising in various states of healing all over his body, wounds to his chest and abdomen, and anal trauma, as CrimeOnline previously reported.

Alexander was charged at that time with injury to a child, stalking, and tampering/fabricating evidence with intent to impair an investigation. Berg was charged with injury to a child.

Court documents said that Alexander, 30, brought Dawson to the hospital on October 14, saying he heard a “thud” and found the boy. But hospital staff said the injuries the child suffered did not match Alexander’s claims and called police.

Police spoke with Berg, 30, who said she left the boy with Alexander at around 7:30 that morning, then later got a text from the boyfriend about Dawson eating lunch. But after lunch, she said, he gave her a panicked phone call saying he was taking the child to the hospital.

Berg said she rushed to the hospital, where Alexander told her the same story about the “thud” he told hospital staff. Police showed Berg photos of her son’s injuries, and she said he didn’t have them when she left for work that morning. Meanwhile, Alexander hired an attorney while at the hospital and refused to speak with police.

Alexander and Berg were both arrested two days later. Alexander has remained behind bars since his arrest on a $250,000 bond. Berg was released on a $100,000 bond at that time, but was taken back into custody after the boy’s death. Both are now being held without bond, jail records show.
