PHOENIX -- An Arizona dump truck driver convicted of numerous charges for the 2010 deaths of four motorcyclists has been sentenced to 26 years in prison.
Maricopa County Superior Court Judge Joseph Welty handed down the sentence Friday afternoon.
Jurors returned guilty verdicts against Michael Jakscht on charges of manslaughter, aggravated assault and endangerment after an August trial.
Jakscht plowed his 12-ton truck into a group of motorcyclists stopped at a north Phoenix traffic light on March 25, 2010. Four motorcyclists died and five others were injured in the fiery accident.
Phoenix police said toxicology tests showed Jakscht had methamphetamine in his system. Jakscht's attorneys had argued that he had taken diet pills and that the brakes on his truck weren't working well.
