Four-year-old Tyrone Champ, who was found critically injured Monday in his Northeast Washington home, died yesterday, and a 24-year-old man was charged with murder in his death, D.C. police reported.

Tyrone, who lived with his mother and three siblings, including a twin, at 1700 Maryland Ave. NE, was unconscious when he was found by police and ambulance attendants about noon Monday, according to police. He died about 8:40 a.m. yesterday, a D.C. General Hospital spokeswoman said.

Terry Theldell Cain, who lives at the same address, was charged Monday with assault with intent to kill and was released on his own recognizance after arraignment in D.C. Superior Court Tuesday, according to court documents.

Police said Cain surrendered about 4:45 p.m. yesterday to homicide detectives at police headquarters and was charged with second-degree murder in Tyrone's death. He is to be arraigned today in D.C. Superior Court, they said.

Police said that Tyrone was apparently the victim of a severe beating. According to court documents, he was in a coma when he arrived at the hospital and was suffering from internal bleeding and trauma to the head and brain.
