Leumas Moraza is facing a murder charge after police said he shot Maria Santiago-Burgos, 43, three times after they were arguing about their relationship.

Kissimmee Police received a 911 call from Santiago-Burgos' daughter just before 10:30 p.m. saying that her mother had been shot. The 38-year-old Moraza called authorities and admitted he shot her, according to a 911 recording and the affidavit.

When he went to police, they said Moraza placed a .9 mm Ruger handgun on the ground and told them he and Santiago-Burgos had began dating in February and had been living at the motel at 1815 West Vine St. since last month.

Eventually, according to Moraza, Santiago-Burgos wanted him to leave the motel they were staying in with her 64-year-old mother and two children. As she was collecting his things, Moraza said Santiago-Burgos reached for her gun and when he tried to stop her, she was shot, a police affidavit said.

But Santiago-Burgos' two minor children and her mother told police that while she and Moraza were arguing, he pointed the gun at Santiago-Burgos and then at them.

The boy ran into a bedroom and shut the door, and Moraza shot Santiago-Burgos in the back, the affidavit said. The mom then dragged her into the bedroom, where Moraza busted in and shot Santiago-Burgos two more times, according to the affidavit.

Police said Moraza told them he didn't remember the second and third gunshots.

In addition to murder, Moraza is also charged with three counts of aggravated assault with a deadly weapon. He's at the Osceola County Jail with no bond.

Anyone with information on the incident is asked to call 1-407-846-3333.
