Philadelphia police are asking for help finding three people who were recently reported missing and whose disappearances have authorities concerned about their well-being.

A fourth person who had been missing and was listed as "endangered" - 16-year-old Leanne Merna, of Castor - was found safe, but police did not say where.

Still being sought were 27-year-old Janine Felts, 72-year-old Doris Blount and 89-year-old Francis Rollins.

She is 5 feet 5 inches tall, 144 pounds and has gray hair. She was last seen wearing blue jeans and a burgundy coat.
