Shirley Mitchell, the actress who played Marion Strong, Lucy Ricardo’s cackling friend on “I Love Lucy” has died. Mitchell is the last-surviving adult cast member. She died at age 94. Reason of death? Heart failure. She passed in her Westwood condo. Marion Strong has this distinction — she set up Lucy and Ricky on their first date. Mitchell was no stranger to sitcoms, but no longer starred in shows. RIP!
