TOOELE — A judge on Monday scheduled a preliminary hearing for the 17-year-old Utah boy accused of shooting and killing his mother and three of his siblings.

Third District Judge Dianna Gibson set the three-day hearing to begin next Jan. 13 to determine if prosecutors have enough evidence for the case to go to a trial.

They allege Colin Jeffery “CJ” Haynie fatally shot his mother and siblings as they returned home in stages earlier this year on Jan. 17, then tried to kill his father, who wrestled the gun away from his son after being shot in the leg.

Haynie appeared in a face mask during the brief hearing held over video, like most other Utah court proceedings amid the coronavirus pandemic.

Gibson said she hopes that by January, it will be safe to hold in-person hearings.

Haynie’s defense lawyer, Richard Van Wagoner, agreed.

“I think ... we ought to do it in person if at all possible,” he said.

Haynie is being held in a juvenile detention center on $4 million bail.

He is charged as an adult with four counts of aggravated murder, a first-degree felony, in the deaths of his mother, Consuelo Alejandra Haynie, 52; sisters Alexis Haynie, 15, and Milan Haynie, 12; and brother Matthew Haynie, 14. He has not yet entered any pleas.

He faces an additional charge of attempted aggravated murder tied to his father’s injuries and five counts of discharge of a firearm, all first-degree felonies. If convicted, he faces at least 25 years in prison.
