The final defendant charged in connection with a 2011 carjacking and murder was sentenced to prison Monday.

Pima County Superior court Judge Kenneth Lee sentenced Luis Francisco Howard to 10½ years in prison following a guilty plea to manslaughter.

Howard was accused of participating in a carjacking on Tucson’s south side near South 12th Avenue and West Drexel Road that left Terry Caldwell dead.

Howard and three other men were accused of attacking and robbing men who a female defendant lured by posing as a prostitute.

Caldwell attempted to ward off the attackers, who fatally stabbed him. He was found dead in the parking lot of a nearby apartment building.

Howard’s attorney, Rick Lougee, said the other defendants inaccurately portrayed his client as a ringleader in the spree of crimes that led to Caldwell’s death.

Lougee described Howard as the “odd man out” in the case.

“He knew there was going to be a carjacking, he didn’t know there was going to be a homicide,” he said.
