Utah Teenager Receives 100-Year Sentence for Methodical Family Massacre

In a case that has shocked the quiet community of Grantsville, Utah, a 16-year-old high school student has been sentenced to 100 years in prison for the brutal execution of his mother and three siblings. Colin Jeffrey "CJ" Haynie carried out the horrific killings over a five-hour period in January 2020, marking the first murders in the town in two decades.

A Calculated and Chilling Sequence of Violence

According to Tooele County Attorney Scott Broadhead, Haynie lay in wait at the family home before beginning his rampage. He first shot and killed his 52-year-old mother, Consuelo Alejandra Haynie, at approximately 1 p.m. The prosecutor detailed that Haynie then systematically murdered his siblings as they returned home from school.

The victims included:

  • Maylan Haynie, aged 12, who was killed alongside her mother upon entering the house.
  • Alexis Haynie, aged 15, shot between 2 p.m. and 5:17 p.m.
  • Matthew Haynie, aged 14, killed execution-style with a single bullet to the head.

Broadhead stated that Haynie used a handgun, firing at the victims' heads, necks, and upper bodies. The father, Colin Haynie Sr., returned home around 6:15 p.m. and was shot in the leg during a struggle where he managed to wrestle the firearm from his son.

Legal Proceedings and Sentencing

Haynie was taken into custody at a local hospital, where he confessed to police, revealing his intention was to kill everyone in the household except himself. Tried as an adult in 2023, he pleaded guilty to four counts of aggravated murder and one count of attempted aggravated murder for the attack on his father.

In a consequential ruling, the court sentenced Haynie to 25 years for each murder charge, to be served consecutively, resulting in a total of 100 years. The attempted murder sentence will run concurrently. Court documents cited the teenager's increasing social isolation, arguments with his father, and unfulfilled expectations as motives for the atrocity.

A Family's Heartbreaking Response and Community Support

The tragedy devastated the Haynie family, with an online fundraiser for the father's medical and funeral expenses surpassing its $100,000 goal. At the funeral service, Danny Haynie, a sibling not present during the killings, remembered his mother, sisters, and brother fondly.

"He is part of our family and we all love him," Danny said of his brother. "We all want the best for him. Part of me feels like I lost him too but at least he’s still here." The funeral program featured family photos including Colin, and the father expressed choosing to focus on positive memories, imagining his children exploring the afterlife under their mother's care.

Four caskets—white for Consuelo, blue for Matthew, and white with purple hues for Alexis and Maylan—filled the church. "Families are eternal and that’s what is going to keep us going," Danny Haynie concluded. "I know we will be reunited again as a family."
