WILMINGTON, NC (WWAY) -- Testimony today focused on test results in the trial of a man accused of hitting and killing two cyclists last year on River Road. Thomas Grooms faces two charges of second degree murder in the deaths of Trey and David Doolittle.
Monday, the jury learned official test results from the State Bureau of Investigation. The jurors also learned what the those results could have meant for Grooms the day of the accident.
Although investigators originally thought the white substance found at the scene was cocaine, the tests showed it was another drug: mephedrone.
Mephedrone was not illegal in North Carolina at the time of the accident, but it is now. Doctors say there are many different effects from the substance, like prolonged irrational behavior that can last for days.
The SBI also said Grooms's blood alcohol content was 0.13 less then two hours after the Sunday-morning accident. According to a mathematical equation, his BAC was 0.16 at the time of the accident, which is twice the legal limit.
Grooms's ex-girlfriend testified today, as well. The prosecution thinks her testimony is important to show the jury that although Grooms was never charged with DWI before this accident, he was warned by someone who cared about him that his actions were wreckless and potentially deadly.
The defense has until Tuesday morning to decide if they will call witnesses to the stand. If not, closing arguments begin.
