YAMHILL, Ore. — A 67-year-old man has been arrested for attempted murder for shooting a man Friday night at a pizza parlor in Yamhill.

The victim, 27-year-old David Trivelpiece, remains in the hospital. He has a bullet lodged in the spine near his neck and is suffering from paralysis on his left side and limited mobility on his right, according to the Yamhill County Sheriff's Office.

The suspect, Richard Mershon, was arrested on two counts of attempted murder, two counts of first-degree assault, unlawful use of a firearm, menacing and harassment.

Yamhill police officer Travis Vancleave wrote in a probable cause statement that Trivelpiece ran from across the street to help after Mershon reportedly fired shots at another person outside Zippy's Pizza at 180 South Maple Street. A struggle between the two men ended when Mershon shot Trivelpiece in the left side of his neck.

The original fight broke out when a man tried to intervene after he said he saw Mershon push a pregnant woman who was trying to give him a ride home because he was intoxicated.

The man told police he stepped in and tried to take Mershon's keys, but Mershon told him he was going to shoot him and then pulled a gun from his waist and pointed it at his chest. The man said Mershon fired two or three shots but they all missed.

Two 9mm shell casings were found at the scene, Vancleave said.

At that point, Trivelpiece ran over from across the street to help and was shot by Mershon.

When Officer Vancleave arrived at the scene at around 9:01 p.m., he found Mershon standing next to his car, holding a 9mm semi-automatic pistol in his right hand. Trivelpiece was lying motionless on the ground next to him. Mershon, who was covered in blood, dropped the firearm when instructed by Vancleave to do so and was taken into custody.

Vancleave went to check on Trivelpiece, who was semi-conscious. He was having trouble breathing and asking for help. He was taken by ambulance to OHSU with life-threatening injuries.

The shooting remains under investigation.
