/*CHP*/ officer Justin McGrory had pulled over a vehicle for speeding near Hodge Road, and while he was talking to that driver, a dark car veered onto the shoulder of the freeway and sideswiped the officer.
McGrory was airlifted to /*Saint Mary's Hospital*/ but did not survive.
The driver of the red 2009 Pontiac G6 that struck McGrory, 18-year-old Rafael Garcia of Las Vegas, was arrested at the scene on suspicion of vehicular manslaughter. More charges could come depending on the outcome of the investigation, authorities said.
The /*15 Freeway*/ was shut down for hours. Nobody else was hurt in the incident.
McGrory, 28, of Victorville, is survived by his wife, Kelly, and their three children, a 7-year-old daughter and two sons, ages 4 and 1.
McGrory's fellow officers saluted his body as it was taken to the coroner's office.
Friends said McGrory was fullfilling his dreams following in his father's footsteps working as a CHP officer in the Inland Empire.
"This is really kind of close to a lot of us," said CHP Sgt. Kevin Eads. "We knew his dad. I worked with him personally here at the Victorville office watching him grow up, so it's tough."
McGrory would have served his third year on the force in October.
"He was a good-natured kid, fun loving," Eads said. "He looked like he'd be a good dad and husband. He looked like he was fun to work with. I wish i would have had an opportunity.
"According to the Barstow-area officers, he was a very likeable person," CHP officer Mario Lopez said. "He got along with everybody, he was a hard worker and he's definitely going to be missed, very dearly."
McGrory is the third CHP officer to die in the line of duty in June.
