HAMMOND, Ind. (CBS) -Friends on Saturday remembered a 16-year-old Calumet City girl who disappeared this week before her body was found in a Hammond, Ind. trash bin a day later.

Jessica Tetter was found at 5945 Hyslop St. in Hammond on Thursday — initially as a “Jane Doe.” She died of trauma to the head and  body, said the Lake County, Ind. Coroner’s Office, which identified Tetter.

A person of interest is in custody with Calumet City police, and is someone known to Tetter’s family.

Friends the teen held a vigil in her memory on the track at Thornton Fractional North High in Calumet City. Tetter was on the track team and also boxed, friends say.

“People thought it was so funny because she was so small,” Kathryne Sneed told CBS 2’s Suzanne Le Mignot.

Tetter was reported missing on Wednesday by her mother. Tetter’s mother said the girl left their Calumet City house around 11:30 a.m. Wednesday and did not return. Calumet City officers searched the area without results.

Officers from the Hammond Police Department provided a photo of a Jane Doe girl found in the trash bin, attempting to obtain an identification. A Calumet City investigator noticed a resemblance between Hammond’s Jane Doe and the nearby Illinois city’s missing girl.
