Police still have not cracked the case involving the 2018 killing of Richard Jefferson's father ... but now, they're hoping a big monetary reward can help change that.
Los Angeles County Sheriff Dept. Lt. Patricia Thomas said on Tuesday they're offering $20,000 to anyone who can assist them in solving the 4.5-year-old case.
Thomas told reporters at a news conference she and investigators believe there are people still out there who saw the suspects that shot 65-year-old Richard Jefferson Sr. in Compton, Calif. back on Sept.
