Sioux Falls Police Captain Blaine Larson says Monday night's murder victim---45-year-old Rodney Lonnie Iron Hawk---was friends with the man charged in the murder. He is identified as Mark James Lovejoy.

"They are acquainted after hearing some accounts from the people we have talked too. They're friends. I mean they hang around together. They stayed a night at the motel before. What actually sparked it last night we don't know for certain."

Larson says a fight started between the two men at the Arena Motel.

After being told to leave the motel by the manager, the fight continued into the motel's parking lot.

Iron Hawk later died at the hospital after suffering blunt force trauma to his face and head.

Lovejoy is charged with assault and homicide.
