An apartment fire in Arlington has led to an investigation into the suspicious deaths of a woman and her infant son.
Arlington police early Monday said the deaths are being treated as homicides.
The Tarrant County Medical Examiner now says 26-year-old Mechelle Gandy died of multiple stab wounds, not the fire. She was pulled from the residence and died later. Her son was found dead in the home.
Her neighbor, Perry Webster called Gandy, "a sweet woman who always stopped to say hello."
Webster said he can't believe someone would want to hurt Gandy and her infant son Asher. "They was always together, every time she left he was always with her. She was never alone, always with him," said Webster.
Webster said he and his neighbors heard screeching tires just before they noticed the fire.
A police statement says the fire was reported around 10:15 p.m. Sunday in the 2200 block of Presidents Corner Drive. Assistant Fire Chief Alan Kassen said the blaze apparently started in the boy's bedroom.
Police initially said the baby was a girl, but spokeswoman Tiara Ellis Richard later Monday updated information on the victims to say the infant that died was a boy.
