Tulsa County jurors last month found Rashad R. Easley, 20, guilty of first-degree murder and four counts of assault and battery with a deadly weapon.

The jury imposed a life term on each count.

At Monday’s formal sentencing, District Judge Tom Gillert ordered that all terms run consecutively.

For parole purposes, a life sentence equates to 45 years, and a person convicted of murder or assault and battery with a deadly weapon must serve at least 85 percent — more than 38 years — of the prison time imposed before becoming eligible for parole. All five of Easley’s sentences have that requirement.

Prosecutors said Easley drove a Mercury Marquis from which a co-defendant, Vincent “Venom” Berry, fired at least 15 shots with an SKS rifle at a southbound Chevrolet Caprice on North Cincinnati Avenue on Sept. 7, 2008.

Donivan Crutcher, 16, was fatally wounded and died the next day.

Easley had recently been shot and erroneously thought someone in the victims’ car was a gang rival who was responsible for his shooting, prosecutors said.

Easley did not testify.

Co-defendant Antonio Wells — who said he was a passenger in the Marquis — testified as a prosecution witness at Easley’s trial.

Wells and Berry have unresolved murder and assault charges. Berry, 20, is slated to be tried alone on Jan. 19.

The shooting left Donivan Crutcher’s brother, Adrion Crutcher, paralyzed.

Jeremy Williams’ injuries include the loss of an eye.

Jahmal Bryant, who was driving the Caprice, was shot in the chest.

A fifth occupant of that car, Victor Bell, was grazed on the arm.
