Seven people total were injured after a woman started shooting into a crowd of people after a midnight cruise on the 'Detroit Princess' riverboat.

The shooting happened Sunday night when a woman left the boat, went to her car and started shooting.

According to the Free Press,

A woman who was on the Detroit Princess riverboat went to her car after getting on shore, retrieved a gun and opened fire early Monday, hitting four of her relatives and friends, officials say.

Another family member who wasn’t on the boat returned fire, critically injuring the shooter’s boyfriend as they were driving away.

As of now police do not have anyone in custody, and ask that anyone with information can call Detroit Police investigators at 313-596-5240 or Crime Stoppers anonymously at 1-800-SPEAK-UP.
