Kristina Aksman, Daniel Baker Sought In Vernon Hills Murder

A murder investigation in northwest suburban Vernon Hills continues Monday as police seek two "persons of interest" in the beating death of a 50-year-old woman.

The police were contacted by Marina Aksman's neighbors Thursday morning, when they noticed a car had driven across her lawn and crashed into her house. When they arrived on the scene, they found Aksman's body, apparently beaten to death. An autopsy showed that she died from blunt force head trauma.

Police continue searching for Marina Askman's daughter Kristina Aksman, 20, and her boyfriend, 21-year-old Daniel Baker of Deerfield. The Chicago Sun-Times reports that law enforcement describes Kristina and Daniel's relationship as "volatile," and that it was a source of concern for Kristina's parents.

A picture of the murder is starting to take shape. The car that crashed into the Aksman home is registered to Baker's mother, and neighbors reported seeing Baker driving the car. A baseball bat believed to be the murder weapon was found at the scene. The Aksman's car, a silver 2009 Nissan Rogue with Illinois license plate 421 9607, has been missing since the murder. Daniel Baker and Kristina Aksman are believed to be fleeing in that car.

But the story is further complicated by Kristina's disabilities. TheChicago Tribunereports:

In March, a judge appointed Marina Aksman as her daughter's legal guardian after a doctor said Kristina Aksman suffered from "a seizure disorder and developmental delay," had received special education at school and was "not fully capable to take care of herself."

It is unclear if she has her much-needed medications. Her role in the murder is also still unknown.

Police are searching for the pair in Lake County, but the search has also gone nationwide, according to theSun-Times. Police have been contacted in Florida and California because investigators believe the pair could be headed to one of those locations.

Though police told the Sun-Times Kristina may be "at risk," Baker's mother says her son is also in danger. According to the Chicago Tribune, Diana Baker, mother of Daniel, has retained the legal services of Ed Genson. Genson is known as a celebrity defense attorney in the Chicago area; he represented R. Kelly when the R & B star was acquitted of child pornography charges in 2008, and for a brief time also defended ex-governor Rod Blagojevich.

"We're just waiting to see what pans out when the children are somehow caught or surrender or come in for questioning," Genson told the Tribune. "Then we'll know where we are."
