MINNEAPOLIS (WCCO) – It has been two years since three-year-old Terrell Mayes Jr. was shot and killed.

Mayes was with his brothers inside their home near 26th and Colfax Avenue in north Minneapolis when gunfire erupted.

The children were running to a safe place when a bullet pierced the side of the house, killing Terrell.

Friday, investigators and Terrell’s mother, Marsha Mayes, are again asking for help in finding the person responsible.

With the reward for information leading to an arrest sitting at $60,000, Mayes and investigators hope it helps get a killer off the streets.

Being on the block where her son’s life was taken is still hard for Mayes, two years after he took his last breath.

“Every day at 6:30, if I don’t hear sirens, I’m on my knees and my face praying, ‘Lord, when is justice going to come?'” Mayes said.

But besides praying, Mayes is also actively searching for any leads that can help police.

“I know you’re tired of running because I’m tired of running with you,” Mayes said.

It’s frustrating for her, as well as for investigators. Deputy Chief Kris Arneson says detectives continue to work the case.

“We’re not getting any new calls, we’re not getting any tips. We really need the public to help solve this case,” Arneson said. “We have doubled our investigators, who are working diligently on this case. We have four investigators assigned.”

Arneson says Minneapolis Police follow up on every violent crime in the neighborhood.

“Every gun that comes in, we run through our own system to see if it’s linked to the weapon that was used to kill him,” she said.

Mayes says time has not healed her heart.

“I feel like I’m lost,” Mayes said.

She believes someone out there knows something, and hopes they find it in their hearts to tell what they know.

“It’s been two years. Give me that closure. Give me that piece of mine,” Mayes said.

Police believe they can only solve this crime with the public’s help. Anyone with information about the shooting can speak out anonymously by texting your tip to investigators at 847411.
