GRANTSVILLE, Utah — A teenage boy shot his mother and sister after she picked up the girl from school, then killed two more siblings as they returned home on a weekday evening, prosecutors said Wednesday.
Collin J. Haynie, 16, was charged with 10 felonies, including aggravated murder and discharge of a firearm. The Associated Press does not typically name juveniles accused of crimes, but the seriousness of the case meant Haynie was charged as an adult under Utah law.
No attorney was immediately listed for him.
The quadruple slaying happened Friday night in the small town of Grantsville west of Salt Lake City.
“He has not talked to the police or anyone in authority, so we don’t really know what he was thinking, what his thoughts were, what his motivations were,” Broadhead said.
Prosecutors planned to meet with Grantsville police on Wednesday, and charges would be filed sometime after that. He is expected to be charged in district court, which has jurisdiction in cases of anyone over the age of 16 charged with aggravated murder or murder.
Authorities have declined to name him or specify his relationship to the victims before charges are filed.
Grantsville police officials have said the teenager is facing as many as 10 charges, including aggravated murder.
Prosecutors would not be allowed to seek the death penalty because the boy is a minor. The possible prison sentence for an aggravated murder conviction is 25 years to life.
The funeral for Consuelo Alejandra Haynie, 52, her 15- and 12-year-old daughters and her 14-year-old son will be held Friday. The injured husband and father, 50-year-old Colin Haynie, has been released from the hospital and was talking with investigators.
The family moved to Grantsville in 2010 and they have two other children, according to an obituary for Alejandra Haynie and the children.
