The body of a missing woman was discovered tied up in a shopping cart in a SW Side alley, according to her family.

A 21-year-old woman who had been missing for months was found dead on Chicago’s Southwest Side on Friday, according to her family.

Rosa Chacon’s body was discovered in an alley in the 2300 block of West 24th Place, tied up and wrapped in sheets, according to her relatives.

“I miss my baby,” her father Jose Lucio said. “Normally when our daughter leaves, we hear from her. She calls the next day, she calls an hour after she leaves, she’s in a house, she’s secure, she’s nice and warm. But we didn’t hear anything.”

“I don’t know how they have a heart to do somebody like that,” said Rosa Chacon, the victim’s mother.

Her family last saw her outside her house on January 18. Chacon is seen in a home security camera video getting into a rideshare in the 2800 block of South St. Louis Avenue. Chacon’s family claimed she didn’t bring anything with her, including her coat and identification.

“She said, ‘I’ll be back mom. I got the Uber ride there and the Uber ride back,’ that’s what she told me,” her mother said.

Her cause of death will be determined by the Cook County medical examiner. Relatives said the tattoos on her body helped them identify her.

“She was the party type. She was not trouble,” said Juan Lucio, her brother.

Her mother said she didn’t know where her daughter was going or who ordered the ride for her and that Uber refused to say. According to a company spokesperson, they do not release private information for privacy and policy reasons.

Meanwhile, the family reported Rosa missing to Chicago police, but their concern quickly turned to anger after authorities failed to assist them.

“The cop said a crime had to be committed for them to do anything,” said Alejandro Guzman, the victim’s boyfriend.

They hired their own private investigator after months of searching and handing out flyers on their own.

Last month, a 20-year-old Guatemalan migrant was discovered shot to death in the same neighborhood.

Reina Cristina Ical was discovered dead in an alley near the 2400 block of S. Drake Avenue in Little Village. Her death was determined to be a homicide.

There have been no arrests in that case thus far.

“Be sure to watch your daughters more closely,” Chacon’s father said. “Don’t trust anybody.”

While Chicago police continue their investigation, community activists are offering a $15,000 reward for information leading to the arrest and conviction of the perpetrator.
