Jessica Suarez, 21, was last seen leaving her home in Chicago's West Ridge neighborhood and getting into her car on February 25, according to a missing person alert from Chicago police.
Her car was found unoccupied and parked at 5100 N. Simmons Dr. on the lakefront the next day, near Foster Avenue Beach, police said.
Family members said police showed them surveillance video of Suarez jogging on the lakefront the morning she vanished.
Officials said the woman's body was spotted at about 4:20 p.m. Saturday about a half mile from the end of the pier.
The Cook County Medical Examiner's office identified the body as Suarez on Tuesday. The cause and manner of death are pending.
