City fire Maj. Les Gay told the jury the fire was intentionally set in a city-issued trash container. But he, too, was unable provide evidence of an accelerant used to start the fire.
“I did not find the source of the ignition,” Gay testified.
Gay told the jury he found remnants of two Molotov cocktails in the street in front of or near the defendant's home along with a Roman candle.
The investigator found shattered Wild Turkey bottles in the street and rolled-up paper towels used as wicks, but said he couldn't tell if the bottles contained flammable liquid or if the wicks ignited the liquid.
Gay also testified about finding burned flannel pajamas next to a trash container where Owen lived with his grandparents about two doors away from the victims.
A witness previously testified Owen ignited the pajama pants in his driveway before the fatal fire.
Jurors visited the scene of the fire Tuesday. The home was torn down and rebuilt, prosecutors said.
