Spanish Fork police, today, are investigating an apparent murder-suicide, that claimed the lives of Bryson Drew, 21, and the 2-year-old son who had been living with him for about three weeks.

Authorities say Drew was sharing custody of the toddler with the boy's mother.  The parents had never been married.

The victims were found inside Drew's grandparent's home -- where they had been living -- shortly before 9 pm, Sunday evening.

Police say it appears the father died of a single gunshot wound, while his son looks to have died from blunt force trauma.

The medical examiner is now determining the exact cause of death.
