A Utah County judge, Monday morning, told Joshua Petersen, 21, he will remain jailed -- without bail -- for the April 5 shooting death of his infant son, Ryker.
Authorities say Petersen told them he shot the boy, because he was distraught over his break-up with the boy's mother.
He also claims he planned to take his own life, but was stopped by family members.
Petersen has been charged with aggravated murder.
His next court appearance is in two weeks.
