JACKSONVILLE, Fla. (AP) - A sailor has been charged with murder in the 2010 death of his girlfriend's son at an off-base military housing unit.
The Florida Times-Union ( ) reports 35-year-old Nicholas James Rivet was arrested Wednesday.
An arrest report says Eddie Robb was found unresponsive in his bedroom. He died from a fractured skull and severe brain injury.
The newspaper reports that police interviews with Rivet and girlfriend Brandi Robb indicated the boy had woken up Rivet's 3-year-old daughter who was in the same room. Robb told investigators she heard a "thud" after Rivet went upstairs to check on Eddie. A couple of hours later the child was found unresponsive.
It wasn't clear what caused the delay between Eddie's death and Rivet's arrest. No attorney was listed on jail records.
