'Loud boom'

Fire officials responded to Friday's fire about 11:15 a.m., authorities said. While there, a Gary detective saw Reginald Carter driving a silver minivan to the west of the scene at a high rate of speed, exit and then run toward the scene. The minivan had a strong bleach smell, court records state.

A family member stated the three victims all lived in the home together, and that Yoasha Carter's boyfriend, Reginald "Slim" Carter, also lived there and that they had a newborn child together, court records show.

Reginald Carter told police he got into argument with Yoasha Carter that morning, but left to take their child to "his people in Chicago." The baby was dropped off at 11 a.m., about 15 minutes before police arrived at the scene of the house fire.

One neighbor told police they heard a man and woman arguing about 9:45 a.m. and saw a white SUV drive away. Another neighbor told detectives she heard a "loud boom" come from the house sometime after the argument.
