The truck driver previously charged in a crash that killed a Livingston County family has been indicted by a grand jury for five counts of aggravated vehicular homicide.

29-year-old Dayren Rocubert was driving a tractor trailer on I-75 in Shelby County Ohio that hit two vehicles on Christmas Eve of last year. Those vehicles carried 32-year old Lauren Hahn, 63-year-old Kimbery A. Siegrist, 32-year-old Jeremy D.R. Boehne, and Boehne’s pregnant wife, Karen Boehne.

The Boehne’s were both former graduates of Hartland High School. Siegrist was a Brighton resident.

The case was forwarded to the grand jury after a toxicology report showed Rocubert was under the influence of amphetamines, cocaine, and methamphetamine at the time of the crash.

Rocubert is set for arraignment in Ohio next week.
