A jury is deliberating in the William Sherwood murder trial. Deliberations will continue Wednesday.

Sherwood, 65, is charged with second-degree murder in the March 2013 shooting death of John Pratt.

The defendant testified Friday that Pratt, a car salesman on a test drive with a customer's vehicle, cut him off in traffic.

Moments later, Sherwood rear-ended Pratt's vehicle at a red light.

He told the court he was in fear after the collision, watching as Pratt got out of his vehicle, approached Sherwood's car and reached in the window.

"He put his left hand on the side of the window. Then he punched me in the side of his head with his right hand. Then he tried to get the door open, I heard a metallic sound. Then he reached in with both hands, grabbed my head and started twisting," testified Sherwood.

He says during the attack his glasses were knocked off his face.

Sherwood says he was in intense pain and was afraid of the much larger man who stood over 6 feet tall and weighed nearly 300 pounds.

Under testimony he showed how he pulled out a .45-caliber handgun he carried in a holster and shot Pratt twice, in what he calls self-defense.

"When I felt threatened for my life, I pulled out my pistol and defended myself," Sherwood told the court. 

Prosecutors tell a different story, saying it was Sherwood who went too far.

In court Monday, the prosecution decided not to present a rebuttal witness and both sides rested their case.
