March 26, 2025

ST. LOUIS, Mo. (First Alert 4) - A retired St. Louis City firefighter, Mark Burnett, told First Alert 4 Investigates that he lives every day feeling like he’s missing a limb after his son was brutally murdered in 2018.


“I told him I loved him, and I’m proud of him. He said, ‘Thanks, pop.’ That’s the last conversation we had,” Burnett said.


Court documents show 27-year-old Matthew Mancini accused Burnett’s son of stealing from him. He then forced Burnett the third to kneel and shot him.
