Friends and classmates held memorial vigils for people killed early Saturday morning in a crash on a Dayton road caused by a suspected drunk driver.

The Montgomery County Coroner's Office identified the victims as Corey Cooper, 18, of Dayton and Christina Jackson, 20, of Riverside.  Jackson's car was struck from behind in ther intersection of Wayne and Wilmington avenues by a car witnesses estimated going 100 miles per hour on the dark city street.

Jackson was a Carroll High School graduate and Cooper was a senior this year at the school.

More than 400 students attended a memorial service for Cooper and Jackson at Carroll on Saturday, according to principal Matt Sableski. Guidance counselors and campus ministers will be available for students on Monday. Alter High School has also made counselors available.

Sableski said the service was attended by the “vast majority” of this year’s senior class, as well as many members of the junior class and family members.

Eyewitness Jordan Seals said, "I've never seen in my life an accident this violent."

Eyewitness Jacob Bonnell said, "He must have been doing a buck ten, buck twenty somewhere around there. From what I heard they didn't even stop. I just couldn't imagine if that was me in the car."

One of the victims died on the scene, and the other was pronounced dead from injuries at an area hospital.

Dayton police say 29-year-old Robert Finkley from Florida will be charged with two counts of aggravated vehicular homicide and a count of aggravated vehicular assault. He was released from Miami Valley Hospital to the Montgomery County jail late Saturday.

Police suspect Finkley was drinking. They'll wait for more testing before determining what if any charges should be filed.
