SALT LAKE CITY -- A young father is being ordered held without bail in the shooting of his 5-month-old son with a rifle.
A judge agreed to keep 21-year-old Joshua Petersen of American Fork locked up until formal charges are filed Friday.
Utah County prosecutor Craig Johnson says a police sergeant testified at Monday's bail hearing that Petersen had been planning for a month to shoot his son, and decided Friday to do it.
Johnson tells The Associated Press the motive for the shooting at a family residence is unclear.
Family members tell Utah news outlets that Petersen was suffering from depression and the recent breakup of his relationship with the boy's mother.
Police say Petersen sought to turn the gun on himself after killing his son, but was stopped by a family member.
