Maryland State Police have charged a man with murder and rape in the death of a 10-year-old Cecil County girl.
Authorities said 29-year-old Richard Madden Jr. was arrested Thursday in the death of Kami Ring.
Authorities said biological evidence linked Madden to the killing, and that Ring died of blunt force trauma and asphyxia.
The girl's body was found Monday in a heavily overgrown field across the street from a home in which she was staying with a couple she considered her grandparents, even though they're not related. Madden is the couple's son.
Madden is charged with first- and second-degree murder, assault and first-degree rape.
Police say the motive isn't known yet. It wasn't immediately clear if Madden has a lawyer.
He was taken into custody Tuesday on drug charges.
