Spencer McDonald, a 30-year-old triple homicide suspect, was arrested in Nevada and is now being held without bond.

Officers arrested McDonald and said he was carrying a sledgehammer-like weapon.

Police said a possible motive for the killings was unclear but two of the victims lived in an apartment at the complex and may have known the suspect.

The workers entered the apartment with their key and the suspect allegedly attacked them.
