A Prince George's County grand jury yesterday indicted Charles M. Wantland on charges of murder, sodomy, carrying a weapon openly and first-degree sexual offense in the June slaying of 12-year-old Donald Alan Henley of Clinton.

Wantland, 40, was arrested June 19, one day after police recovered Henley's body from a wooded area near his home at 9111 Dixon Dr. Henley, last seen at about 4 p.m. June 17 walking home with a friend, had been stabbed 14 times.

Wantland is being held in lieu of $500,000 bond at the County Detention Center. No trial date has been set.

If convicted, Wantland could be sentenced to up to life imprisonment on both the murder and first degree sexual offense charges. He could receive additional terms of up to three years on the weapon charge and 10 years for sodomy.

A first-degree sex offense involves violence or teh threat of violence, a state's attorney's office spokesman said.

Wantland was convicted of second-degree murder in 1972 in the burning death of Ronald Huss, a drifter who allegedly got into a fight with Wantland in an abandoned Baltimore ware-house after the two had been drinking.

Wantland was paroled from the Patuxent Institution for Defective Delinquents three weeks before the Henley killing, and had been working as a carpentry instructor in a federally-funded job program at a homestead less than a mile from where the boy's body was found.
