Tampa, Florida -- Police are searching for answers in the horrific death of a 4-year-old boy.
Investigators say Marterrance Albury, 4, rolled from a moving SUV that had been driving south down Florida Avenue near 109th Avenue Sunday night. He died early Monday morning at a hospital.
Police say the boy's 17-year-old brother was supposed to be babysitting the child.
Another driver watched in horror as the little boy either fell or was pushed from the back seat of an SUV. Investigators are searching for the SUV's driver, who then ran over Marterrance and never stopped to help. It happened right outside of Parkview apartments, where the family lives.
"That's so sad that's him, that's really sad," says neighbor Marcos Cruz. Cruz is devastated by the death of his young downstairs neighbor.
On Monday, little jeans and shoes remained on the outside patio at the apartment where Marterrance lived with his mom and older brother.
Police say on Sunday night, Johntea Williams, 36, left her 17-year-old son in charge of his brother's care so she could have a fun night out with a girlfriend.
"If you want to enjoy your life, you should not have kids, because kids come first before anything in the world," Cruz says. "His mom should be responsible. As a parent, you don't leave your kids with another baby, 17 years old or 20. No one's going to watch your kids the way you're going to watch him."
Police are investigating how Marterrance wound up in the back of the SUV and who it was that was driving.
"All of a sudden, the back passenger door swings open and the child rolls out," says Tampa Police Department spokeswoman Laura McElroy. "And then the back tires of the vehicle immediately roll over 4-year-old Marterrance Albury."
Paramedics rushed the little boy to the hospital. Nearly a half hour later, his brother came forward to police. It wasn't until 4 in the morning his mother came home to be told that her son had died.
Officers hospitalized her, after she threatened to end her life. "We still have a lot of questions for the mother, but she's in a very hysterical state," says McElroy.
Police are questioning the 17-year-old brother, but say he's mentally challenged, which is slowing the investigation.
Records show officers responded to the family's apartment for a battery in April. Neighbors tell 10 News they've witnessed problems between Williams and the teen, and insist he never should have been allowed to watch his little brother.
"We hear, 'Call the cops, he's hitting me' and she was running out there with her shirt ripped up and everything," Cruz recalls of the April incident.
Cruz remembers Marterrance as a happy little boy. "Every time we'd see him in the window, he'd always wave to us. He did not deserve to die."
Detectives have been checking security cameras from businesses along Florida Avenue for pictures of the SUV. The witness describes it as a 2001-2004, green Ford Expedition.
Police are investigating Marterrance's death as a crime and still weighing who could face charges.
A surveillance camera at a nearby car lot captured video of the vehicle fleeing southbound on Florida Avenue.
Based on the video, detectives are searching for a dark green, possibly black
2000-2004 Ford Expedition. Anyone with information about the car is urged to call Crime Stoppers at 1-800-873-tip or the Tampa Police Department at 813 231-6130.
