SIOUX FALLS, S.D. — A South Dakota teenager has been sentenced to about 1 ½ years in jail for causing a fatal crash following a drug dispute — a punishment the victim's family says is too lenient.

The Argus Leader reports that 17-year-old Alex Lingor, of Sioux Falls, was sentenced Tuesday for manslaughter in the February 2017 death of 15-year-old Kareem Cisse.

Authorities say Cisse and two others stiffed Lingor during a $25 marijuana deal and Lingor chased after their car in his truck, hitting it and sending it crashing into a tree.

Cisse's parents say the sentence isn't adequate justice.

The judge drew criticism from the victim's family and friends last month when he granted Lingor a furlough so the boy could attend graduation. Lingor decided to skip the ceremony.
