ALBUQUERQUE, N.M. (KRQE) – A 13-year-old was shot dead in downtown Albuquerque on an early August morning; another teenager was shot in the leg—but why? With no clear motive, it seemed to police that the suspects vanished into thin air. However, after sifting through hundreds of hours of video footage, a break in the case came from an unusual place.

The intersection at Fifth Street and Coal Avenue is where the shooting happened two months ago; and earlier this month, APD arrested their suspect in Rio Rancho. "The victim was a 13-year-old. By all accounts, an innocent victim. Just seemed like he was hanging out with a couple friends of his, just driving around on a Saturday night, just hanging out being a kid," said Jordan Moenaert, detective with APD's Homicide Unit. On August 18, just before 3:30 a.m., police were initially called out to a crash in downtown Albuquerque on 4th Street and Atlantic Avenue—but, they got diverted to a more serious scene near 5th Street and Coal Avenue. "The officers that were actually en route to the vehicle crash were flagged down and located the victim's vehicle that had been shot a significant number of times," Moenaert said. In the passenger seat, 13-year-old Michael Tubb was dead on scene. His friend, also a teenager, was shot in the leg. The police report says surveillance cameras caught a car pull up next to the victims on the passenger side; then, there was a muzzle flash and sparks. Moenaert's phone rang an hour later. "I think it's important to treat every case with the same amount of importance," Moenaert said, "But, it's hard not to have an emotional response to a 13-year-old child being murdered." The case was a tricky one, Moenaert said, because there were no obvious leads—no connection between the victims and anyone who would want to hurt them. "I really had nothing to go off of to start this investigation and that made it extremely difficult," Moenaert said All police had was grainy footage of the car. "We had collected camera footage from I think probably over, well over 75 different cameras; and I spent a significant amount of time reviewing just hundreds of hours of video," Moenaert said. Unfortunately, none of the camera angles showed a license plate; even after identifying the car as a Lexus sedan and researching it from all angles with APD's Digital Intelligence Team, the trail went cold. "I really started to believe that um, that this vehicle was just, was just a ghost. It felt like it didn't exist," Moenaert said. At a loss for leads, Moenaert began checking Facebook Marketplace every day in the hope that the sedan would show up—and then, more than a month after the crime, Moenaert spotted it: "There was definitely a sigh of relief just knowing that there was the potential for us to have located this vehicle that we spent so many hours just working to find." It matched the photo of the car seen in the surveillance footage based on a few unique details. Through vehicle registration and other data, police connected the car to 22-year-old Michael Flores. "I worked with our digital intelligence team, we utilized one of our undercover Facebook accounts and we sent a message to the profile that listed this vehicle for sale," Moenaert said Then, through that conversation we were able to positively ID at least the vehicle." "We had identified the suspect on September 24 at about 4:00 pm," Moenaert said. A search warrant on his phone put Flores near the scene of the crime close to the time of the shooting; and, by analyzing a photo of the car posted to Facebook Marketplace, police were able to figure out where Flores was staying. KRQE News 13's Natalie Wadas rode along Moenaert as SWAT converged on Flores and arrested him on October 3. Another SWAT operation turned up the Lexus sedan, but the gun has not been found. While pieces of this investigation are coming together, there is still a huge unsolved question: "A very young juvenile victim that was brutally murdered and shot in downtown Albuquerque. We still, through the course of this investigation, haven't identified a motive yet," Moenaert said. Michael Flores was indicted on a count of first-degree murder, tampering with evidence, and conspiracy. Police do believe other people were involved, and are still investigating. The judge released Flores on a GPS ankle monitor.
