Police said they arrested 21-year-old Mykell Lerch on Friday and charged him with murder.
Investigators say Lerch was arguing with his roommate, 32-year-old Mark Zeigler around 7 a.m. Thursday, when the fight turned violent and Zeigler was strangled.
Authorities say a neighbor called police about the fight, and officers found Lerch with a bite mark and scratches on his arm. Investigators say the marks appeared to be made by someone desperately trying to pull an arm away.
Lerch is being held at the Lexington County jail. It wasn't known if he had an attorney.
