SAN CLEMENTE – A 46-year-old woman was arrested on suspicion of murder Tuesday in connection to a deadly hit-and-run crash that killed a 76-year-old grandmother last year, authorities said.

Marthann Demchuk of Monrovia was walking with her grandson along the bike lane of El Camino Real when they were hit by a car on the Fourth of July last year. Demchuk was pronounced dead at the scene. Her 13-year-old grandson suffered minor injuries.

Officials from the Orange County Sheriff’s Department said the two were hit by the driver of a white Volkswagen van, who continued going after the crash.

On Tuesday, Kelly Michelle Wolfe was taken into custody in her Dana Point home, more than a year after the deadly crash.

Officials said a witness followed the van after the crash last year, and Wolfe was interviewed. A DUI investigation was also made at the scene.

An arrest warrant was issued for Wolfe this week on suspicion of multiple felony charges, including second-degree murder, hit-and-run injury, driving under the influence and causing injury, and being an unlicensed driver.

Bail was set at $1 million.
