DENVER - A memorial sign was posted Friday where a DU graduate student was run down and killed as he walked his bicycle across a busy street near the university last year.
The man who hit 24-year-old Masoud Bahramisharif was sentenced to 18 years in prison on Thursday after he was found guilty of vehicular homicide and leaving the scene of an accident resulting in death.
Denver police arrested Andrew James Simpson a few days after the crash. They said they believed he was driving a red Jeep that hit Bahramisharif in a crosswalk and dragged the victim's bicycle for at least a mile, as Simpson fled the scene.
On Friday, a memorial sign was erected at University Boulevard and Evans Avenue honoring Bahramisharif.
-- Deadly Crash --
Investigators said Bahramisharif was walking his bicycle in a crosswalk near the DU campus when the SUV ran a red light and slammed into him on May 31, 2012.
Bahramisharif was thrown about 100 feet by the impact, according to police.
His bicycle was found a mile away, near Asbury Avenue and Colorado Boulevard.
"My son didn't live his complete life. He had so much more living to do," Masoud's mother, Parvin Zamanian told 7NEWS.
Zamanian had flown from Iran to visit her son in Denver when he was killed.
-- Long Criminal History --
Simpson has a 19-year criminal history in Colorado, including arrests for assault, domestic violence, theft, felony drug possession and parole violation, according to public arrest records reviewed by 7NEWS.
Simpson had been sentenced to state prison twice before -- once after pleading guilty to felony drug possession in Denver in 2003. The same year he was sentenced to prison after pleading guilty to attempting to provide false information to a pawn broker in Arapahoe County.
