JACKSON — The trial of an Oak Hill man charged with vehicular homicide in the death of a South Point child has been postponed for the fifth time.

Christopher Haines, 31, was scheduled to go before a jury Monday in Jackson County Common Pleas Court, but motions filed earlier this week by his attorney, James. T. Boulger, have delayed the start of the trial.

“We are asking the court to make a pretrial determination of the admissibility of a prospective witness for the state,” Boulger said.

Boulger said he wanted to question whether or not the opinion of the toxicologist for the state, from the Miami Crime Laboratory, has sufficient evidence to conclude that Haines was impaired by drugs or alcohol during the accident in December 2010.

Haines was driving on State Route 93 when his car rear-ended a car driven by South Point resident Marsha McGinnis. McGinnis’ 10-year-old daughter, Angel, was also in the car. Angel died at Cabell Huntington Hospital later that day.

At the time of the accident, the Ohio State Highway Patrol said Haines had been under the influence of drugs.

Boulger also filed a motion to get more data from the State Patrol Crime Laboratory on Haines’ urinalysis.

There is no date set for the hearing because of a scheduling conflict with the defense’s prospective expert witness, a pharmacist and forensic toxicologist.

A new trial date has also not yet been set.

The trial will be prosecuted by Paul Scarcella and Emily Pelphrey from the Ohio Attorney General’s Office. Both declined to comment on the ongoing case.
