The gunman and a woman were found dead inside a St. Clair Shores home after a standoff with police that started Thursday night, police said Saturday morning.

After several hours of negotiation, S.W.A.T. officers entered the residence at 2:30 a.m. Saturday and found the 58-year-old man dead. Officers also located a 60-year-old woman inside the home.

The cause of death for the two has not yet been determined.

The standoff started Thursday night on the 31900 block of St. Margaret Street after a 62-year-old St. Clair Shores woman and a girl from Detroit were shot.

Police said the man became upset when his neighbor and her family started shooting off fireworks and lighting sparklers.

"As officers arrived on the scene, the suspect fled into an area home and continued firing shots at both officers and civilians," police said in a news release issued Friday night.

"St. Clair Shores officers quickly identified and surrounded the home where the suspect was at and immediately attempted to negotiate his surrender. Although brief contact was made with the suspect, he refused to exit the residence."

WXYZ-TV reported that a tactical vehicle rammed into the house leaving significant damage. Police also launched bomb unit robots and tear gas into the residence, and even attempted to fill the home with water to get the man out.

Police said the man continued to fire multiple times at officers throughout the negotiation process.

Meanwhile, the two victims were transported to a local hospital where they were both treated for non-life-threatening injuries, said police in the news release.

Throughout the entire standoff, neighbors were on lockdown as they were told to stay inside their homes and away from windows and doors until the situation was over.
