Barricades blocked entry to an area of Funks Grove Nature Preserve last summer after the body of Teresa Poehlman of East Peoria was discovered there by hikers. Poehlman's daughter, Christine Roush, and her friend, Matt Isbell, are charged with her murder.

BLOOMINGTON — One of two suspects charged with murder in the death of a woman in rural McLean has been found mentally fit to stand trial.

A psychiatric report reviewed by a judge Monday concluded that Christine Roush, 22, of Washington is mentally fit to stand trial on charges that she killed her biological mother, Teresa Ann Poehlman.

The victim's body was found July 2 by people walking at the Funks Grove Nature Preserve between Shirley and McLean. Poehlman, 47, of East Peoria had been stabbed.

A Dec. 20 status date is set for Roush, who remains in custody in lieu of posting $400,035.

Roush's co-defendant, Matt Isbell, 20, of Marquette Heights claimed to police that Roush planned and committed the murder, according to McLean County State's Attorney Jason Chambers. Isbell knew Roush was going to kill her mother and the reason for the trip to the wooded area southwest of Bloomington, said the prosecutor.

Police also said Isbell provided information of a third potential suspect who knew details of the fatal assault and was seen on surveillance video with Roush before the slaying. That suspect has not been arrested.

In a recent hearing related to Isbell's bond, defense lawyer Alison Motta described her client as "merely a witness to the murder." Isbell's bond was lowered from $3 million to $1 million, meaning he must post $100,035 to be released.

Motta backed away from her earlier claim that the state was aware of alleged threats towards Isbell and his mother received since he has been incarcerated. Roush attempted to solicit another inmate to harm him, said Motta.

Jail officials and the state's attorney's office denied any knowledge of any threats against the murder suspect.

Poehlman's alleged threat to tell police Roush was a prostitute was the motive behind the murder, according to Isbell's lawyer.

Isbell is due in court Dec. 15 for a status hearing.
