Mary Spears, 27, was at the American Legion Joe Louis Post No. 375 on the east side of Detroit when the 38-year-old suspect allegedly approached her and began talking to her, according to WDIV.
When the suspect asked for her number, Spears, whose fiancé was also at the event, told him she was already involved with someone, WJBK reports. The suspect, however, continued harassing her, family members told the station.
Police said security took the man out of the club through the back door and escorted him to the front. After a fight broke out, the suspect allegedly took out a handgun and began shooting, killing Spears around 2 a.m. Sunday.
