A Tooele County teen charged with fatally shooting four of his family members when he was a juvenile pleaded guilty on Tuesday.

19-year-old Colin Jeffery Haynie, who goes by Jeffery, entered guilty pleas to four counts of aggravated murder for the deaths of his mother and three younger siblings. He also entered a guilty plea for the attempted aggravated murder of his father.

Jeffery Haynie was 16 at the time of the murders.

Tooele County Attorney Scott Broadhead said Jeffery Haynie methodically shot his five family members as they each arrived home over a period of five hours on Jan. 17, 2020.

“This young man killed his mother, his three siblings, he tried to kill his father. These were brutal crimes …. neighbors and friends were shocked. It’s just been tough emotionally for many people,” Broadhead told KUTV.

His father, Colin Haynie, was the last family member to arrive home. Jeffery Haynie reportedly shot and injured his father, and a struggle ensued. Colin Haynie was eventually able to get the gun away from his son.

A family acquaintance drove Colin and Jeffery Haynie to an area hospital, where Jeffery Haynie was arrested.

He was formally charged Jan. 22, 2020, for the deaths of Consuelo Alejandra Haynie, 52; Alexis Haynie, 15; Matthew Haynie, 14; and Milan Haynie, 12; as well as the attempted aggravated murder of Colin Haynie.

Jeffery Haynie has an adult brother, who was at college at the time of the shooting.

The teen suspect initially refused to cooperate with investigators. While he told police he intended to kill everyone in the house except for himself, he has still not disclosed a motive.

Broadhead said the case was delayed extensively due to the COVID-19 pandemic and negotiations between attorneys.

“Especially in a case like this, it’s really hard to have a lot of hearing, especially substantive hearings, with somebody of that age and not being able to talk to somebody in person,” Broadhead said.

A sentencing hearing has been set for Dec. 7 of this year. Haynie faces 25-years-to-life in prison for each of the five counts against him.

It will be determined at sentencing whether those sentences will run consecutively or concurrently.
