Live: Defendant Brett Parker Taken By Ambulance After Courtroom Outburst

Brett Parker, an Irmo man on trial for a double-murder, changed his story about the shootings that left his wife and gambling partner dead inside his Ascot Estates home last April, according to testimony during trial Wednesday.

Two family friends of Tammy Parker, Brett Parker's wife, testifed that Brett Parker told them conflicting versions of what happened on the day of the shootings, according to WIS. 

The two family friends say that the first time Brett Parker told his story, he said that Capnerhurst, who was at his house to collect money Brett Parker owed him, forced him at gunpoint to the safe in the attic, according to The State. Parker said he grabbed a gun and shot at Capnerhurst with his arm behind his back. 

The second time he told the women what happpened, he said he grabbed the gun, turned and shot at Capnerhurst straight on, according to The State. 

Brett Parker's attorneys say he acted in self-defense when he shot Capnerhurst.

But prosecutors say that's not what happened. They say Parker devised a “premeditated” and “cold-blooded” plan to kill his wife to collect more than $1 million in insurance money to pay off his gambling debt.

It was also revealed Wednesday that Brett Parker searched Orbitz for a one-way flight to Memphis the day before he turned himself in, according to a report from WIS.
