Scores gathered Sunday in the 2600 block of Colfax Avenue N. in Minneapolis to mark Terrell Mayes Jr.'s fourth birthday.
Terrell was killed by a bullet that strayed into his home the day after Christmas.
Many children were among the neighbors who congregated on a grassy lot to remember his life and to plead again for information about his killer. Community leaders urged the crowd to transform the often-troubled area into the kind of neighborhood they long for.
"It's been seven months, and my family needs closure," Terrell's mother, Marsha Mayes, told neighbors standing or sitting on lawn chairs in the shade of a big locust tree on the warm afternoon.
Nearby stood the light blue house where Terrell was shot. A bullet hole pierces the siding near where he was hit once in the head as he and his brothers ran upstairs to hide in a closet after shots rang out that day.
"My mission today is that the killer would turn himself in," Mayes said. She and her other three sons, ages 2, 11 and 12, have moved to a Minneapolis suburb. The 2-year-old still asks about Terrell, she said.
Mayes said her Christian faith has helped her deal with the grief. And Sunday's strong turnout by community members spoke to her of "the love for my son," she said.
Police spokesman Sgt. Steven McCarty said there have been no recent breaks in the investigation. A reward of $11,285 for information has been raised, and billboards with Terrell's face have gone up around the city.
