The lawyer for a Utah man accused of fatally shooting his 5-month-old son is "devastated" about it.

The Salt Lake Tribune reports that (http://bit.ly/YKJeGC ) 21-year-old Joshua Petersen, of American Fork, made his initial court appearance Monday in Provo.

Prosecutors say they'll decide about the death penalty after Petersen is arraigned and enters a plea to the charge.

Petersen is accused of placing his son, Ryker, on a sofa and shooting him in the head with a rifle on April 5. Police say Petersen then tried to kill himself before a family member stopped him.

Investigators say Petersen was upset when his girlfriend broke up with him, and plotted for a month to shoot his son.
