A Nevada woman fatally stabbed her roommate because he kept talking while she was watching a television show, police say.

Dymund Ellis, 19, of North Las Vegas, was "arrested and booked for a charge of murder with a deadly weapon" in connection with the stabbing death of her roommate, Jace Trevon Ernst, 25, KVVU reported.

Ellis and Ernst got into an argument on May 4 because Ernst kept talking over the dialogue of the television program, according to a police report. It was not immediately clear which television show Ellis was watching.

Ellis told her roommate to “shut up” and Ernst replied, “Shut up, [expletive].”
