A 76-year-old man is accused of causing six separate wrong-way collisions on Interstate 17, including one that killed a 50-year-old motorcyclist on Independence Day, according to authorities.

Darroll Wayne Roberts was being held Wednesday in a Yavapai County jail on suspicion of vehicular homicide while driving under the influence.

Additional charges may be forthcoming, officials said.

Roberts was spotted driving a red SUV north in the southbound lanes of I-17 near Black Canyon City at about 2:30 p.m. Tuesday, said Trooper Kameron Lee, a spokesman for the Arizona Department of Public Safety.

Roberts is suspected of causing six wrong-way collisions along the way, one of which resulted in the death Cindy Lee Meade of Phoenix, Lee said.

The investigation closed the highway for about five hours.
