“I just snapped.”

That is what Kyle Miller, 30, told his aunt after he had stabbed his father to death on the night of April 2, 2011.

Miller is on trial for the murder of his father, Frances Davis.

Davis, 53, was stabbed once in the chest at a home the men shared in the 4500 Block of Lyceum.

Miller’s aunt, Helen McElreath, testified that Miller called her the night of the stabbing.

Prosecutors played that call for the jury on Thursday.

“He jumped on me and I just snapped,” Miller said during the phone call. “I went and grabbed a knife out of the kitchen drawer and I stabbed him in the chest.”

San Antonio police Officer Jennifer Morgan, the second officer on the scene that night, said that Miller told her that the men were arguing over money.

“Him and his dad were fighting over money -- $200 dollars they had to pay in rent,” Morgan testified that Miller said. “And that he didn’t have any money left over and he got upset.”

Closing arguments in Miller’s trial are expected on Friday in Judge Mary Roman’s 175th District Court.

If he is convicted, he is facing a maximum punishment of life in prison.
