Neighbors, friends, domestic violence advocates and elected officials walked in a quiet Rosedale neighborhood Monday night to support a family that’s been ripped apart.

The Christmas Eve shooting on the unit block of Breslin Court killed 4-year-old Jacobi Jones, and injured his 1-year-old sister and his mother, Promyss Marcelle, who attended the walk. Marcelle and the two children were lying in bed in their apartment when the children’s father came in and started an argument at 6 a.m., charging documents state. Jacobi asked his father to leave the home, according to documents. Mark C. Jones Jr. got a gun from a backpack, loaded it and fired on his family, they say.

Jones is being held without bond on charges of first-degree murder, first-degree child abuse resulting in the death of a child under 13, first-degree child abuse resulting in severe physical injury, attempted first-degree murder, first-degree assault and firearm use in a felony or violent crime.

His 1-year-old daughter was shot in the shoulder. Marcelle, the children’s mother, was shot in the head. Jones had a self-inflicted gunshot wound to the face, according to police.

After the incident, Jones called his mother and told her, “I couldn’t take it anymore,” according to charging documents.

Police had responded to the home the night before the shooting for a verbal dispute but didn’t remove 30-year-old Jones.

During Thursday’s community walk around the Ross Ridge neighborhood, Baltimore County Police Chief Robert McCullough referred to Jacobi specifically, saying, “His life was lost before his life had even started.”

Maryland Del. Carl Jackson, a Democrat who represents the area, brought up the idea of the community walk to begin the healing process, he said. Jackson also pulled in resources for any potential domestic violence victims in attendance from TurnAround, a domestic violence services group, as well as behavioral health experts from the MedStar Franklin Square Medical Center.

“Incidents like this make you want to hug your loved ones a little closer and a little longer,” Jackson said.

He said he wanted to learn more about the issue to “be a part of the solution.”

Community members wanted to support the family, even if they had never met them. Sheila Green, a manager of the Rosedale post office, said her mail carrier delivered to the residence. She said she wanted to bring a sense of community after the devastating incident.

“If you have a heart, you’re touched,” Green said.

Kim Ross, the president of a nearby homeowners’ association, said she put out a message to her neighborhood letting them know what happened just a couple of streets over. “People were absolutely shocked,” she said.

“It’s a wake-up call for all of us,” she said.

A GoFundMe fundraiser for Jacobi’s funeral expenses posted by his mother has exceeded its goal of $20,000. More than 1,200 individual donations have raised nearly $32,000 as of Monday evening.

Marcelle was overwhelmed by the support, saying she felt loved and was at a loss for words at the end of the walk. She broke down crying during her statement to the crowd and was immediately comforted by a chaplain, as well as personnel from TurnAround and the Family Crisis Center.

A family friend, Marque Coley, told The Baltimore Sun that Marcelle’s daughter, a once social little girl, now only wanted to be near her mother.

Jones is scheduled for a preliminary hearing on Jan. 24.

Another fatal domestic violence incident was reported in the county days later in Pikesville, when a man is alleged to have stabbed his mother to death on New Year’s Eve.
