Nearly a year after a 31-year-old mother was gunned down outside her Northeast Side home, the man accused of her slaying is heading to trial.

Opening statements are slated to begin Tuesday, Oct. 25 in the murder trial of Jermaine Arnet Cooper.

He’s accused in the shooting death of his girlfriend, which was witnessed by Grand Rapids city workers cleaning streets in the Northeast Side neighborhood in the predawn hours of Nov. 6.

Melissa Moore, who worked at Coral Gables Resort in Saugatuck, was a mother of two. She was shot shortly after 4 a.m.

Cooper was arrested in Detroit a month after the slaying following an eight-hour standoff.

In testimony earlier this year, the slain woman’s 15-year-old son testified that Cooper spent several hours arguing with Moore about a cell phone.

“Yeah, they were arguing about that most of the time - all day,’’ the boy testified.

Cooper, 36, is accused of gunning down Moore on Knapp Street near Truxton Drive NE before fleeing to Detroit.

An earlier hearing included testimony from a city street crew who watched the shooting. Cooper returned from Atlanta about two weeks before the slaying, according to testimony.

Moore fought with Cooper throughout the afternoon of Nov. 5 and into the evening, but the woman’s school-aged sons said it did not turn physical.

The older boy said he received a text message from Cooper at 4:46 a.m. the morning of Moore’s death. In the text, Cooper asked the teen to look after his younger brother and stay involved in sports. It ends: “Tell grandma and the family I’m sorry. I love y’all.’’
