Michael Davis, the 19-year-old brother of 49ers tight end Vernon Davis and Dolphins cornerback Vontae Davis, has been charged with first-degree murder in the family’s hometown of Washington, D.C.

Police say Michael Davis killed 66-year-old Gary Dederichs by hitting him on the head with a hammer on April 24. That was the first of five attacks in the area in which a man fitting Davis’s description hit someone in the head with a hammer. The other four victims all survived but were left with injuries.

On April 26, Davis was arrested by police responding to cries of help from a woman with a head injury. As Davis attempted to flee he threw a backpack that contained a hammer.

Davis has been held in jail since that arrest on two charges of assault with intent to kill while armed. He is scheduled to appear in court on Friday.
