POLSON, Mont. -

A Polson man is charged with raping and drowning an Elmo man who died in late May at Wild Horse Hot Springs just outside the town of Hot Springs.

KERR-AM reports 29-year-old Melvin Madplume Jr. surrendered to Lake County authorities Thursday morning, three days after District Judge Kim Christopher issued a warrant for the May 26 death of 26-year-old Lawrence Kenmille. Madplume is charged with sexual intercourse without consent and deliberate homicide.

Prosecutors say Madplume initially told investigators that Kenmille had fallen and hit his head, causing his death. An autopsy determined Kenmille had drowned due to homicidal violence and another man told investigators that Madplume had made unwanted sexual advances toward him at the hot springs the previous weekend.

The arrest warrant says Madplume is to be held without bond.
