CHICAGO — The family of a woman missing three weeks before being found dead in a garage is speaking out.

Relatives of 26-year-old Shantieya Smith said they are frustrated and feel disrespected by police.

Wednesday, Smith’s family was at the police department hoping to talk to a detective about the case. They say they haven’t been updated about the investigation.

Dental records and tattoos were used to identify Smith, whose body was found under a car in a garage in the 1800 block of South Central Park Avenue last Thursday.

She had been missing since May 25. She left her cellphone and her 7-year-old daughter at home and never returned. Her family said she left with a man who they think is suspicious.

Smith was one of six girls to be reported missing in Lawndale since this spring.  15-year-old Sadaria Davis was found dead in an abandoned building. Police say the four other girls have been found and are safe. None of them were kidnapped.

Police say they are actively looking for a suspect related to Davis’ case. They are not saying that the death of Smith and Davis are related but they are investigating every possibility.
