Crime Stoppers: Man seeks justice for brother killed 10 days before Christmas, $25K reward offered

MILWAUKEE (CBS 58) -- A man who lost his brother to gun violence hopes not only to solve his murder but to change lives at the same time.

Two major missions that he can't accomplish alone, but the hope is by getting rid of a code that's embedded in the streets, he can end the same stupid cycle of violence that killed his brother 10 days before Christmas.

"He is charismatic, warm, genuine, loyal to the point of fault. He's a protector," said Monte Mabra.

When Monte Mabra talks about his brother, Latroy Harris, he doesn't speak as if he's gone.

"I made a vow that we wouldn't give him a death date," said Mabra. "We are trying to create an initiative that will keep his legacy moving forward." 

That initiative is called "I Will Not Die Young."

"The goal is to reduce gun violence," said Mabra.

It's a 20-course program for anyone who uses guns illegally or feels empowered by them.

"It will do that by showing the cause and effect of gun violence. The effects it has not only on the victimizer but on the victims' families left behind," Mabra said.

Mabra hopes to teach empathy and end the cycle of revenge.

"The street code has a belief that you have to get a get-back. And that get-back has no expiration date," Mabra said. "I want to challenge those distorted beliefs."

Family

In fact, Mabra says that's why his brother was murdered.

"Years ago, almost a decade ago, a fight occurred between an individual and my brother," Mabra said.

Milwaukee police say on Dec. 15, 2025, Antonio D. Brown walked into Dee's Elegance Bar and shot Latroy Harris multiple times. Brown's been charged with murder but is still on the run.

"I don't seek any revenge or ill feelings towards him, I just want him to be brought to justice," said Mabra.

Milwaukee Crime Stoppers President Michael Hupy has put up a $25,000 reward to encourage anybody who knows where Brown is to come forward anonymously.

"You have one of two choices, you can be a part of the problem or part of the solution," said Mabra. "There's no in between. There's no gray area. Stop believing there is a gray area."

It was those words from a probation officer turned mentor that helped Mabra become part of the solution after living a life of crime.

Ever since, Mabra has been helping fractured families through the Fatherless Child Initiative.

"My brother's life has taken a different course," he said.

At 46 years old, Latroy had just started helping Mabra help others.

"Was on his way to receive domestic violence facilitation training," said Mabra.

After making a vow to himself to never go back to jail.

"He was trying to change the course of his life, and the day before his training, he was killed," said Mabra.

Now, we'll never know the good Latroy could have done in Milwaukee.

Mabra believes we may see the good Antonio Brown can still do -- but that depends on you

"I want to see him brought to justice," said Mabra. "I want to see him be given an opportunity that he didn't give my brother."
