A baseball bat that investigators believe was used to beat 50-year-old Marina Aksman to death has been recovered, investigators say.
Police discovered Aksam dead in her Vernon Hills home Thursday after being called to the residence in the 1800 block of Olympic Drive to investigate a car that had crashed into her front porch.
Police said they were expanding their search nationwide for Daniel Baker and Kristina Aksman, the victim's daughter, who police earlier labeled as a person of interest in the crime, but now describe her as "missing and endangered."
“She may be at risk -- She has physical and mental disabilities," Vernon Hills Police Sgt. Pat Zimmerman said, according to the Chicago Tribune.
Police have received close to 100 leads.
"I think we're getting closer. We're hopeful we'll bring them in by the end of today," Zimmerman said.
Police say they do not know if Kristina Aksman has her medication to treat seizures and isn't fully capable of caring for herself. A judge recently appointed her mother as her legal guardian and police said they aren't yet sure if she's a suspect in the crime or a victim herself.
Aksman's husband, a delivery truck driver, was not at home at the time and is cooperating with police, Zimmerman said, according to the Chicago Tribune.
Baker and Kristina Aksman were last seen at about 11 p.m. Wednesday in Baker's Deerfield home.
