Waterloo, IL (KSDK) -- Attorneys for accused killer Chris Coleman are working to block a push by prosecutors to allow his murdered wife's texts as evidence.
Christopher Coleman is scheduled to stand trial in February in Monroe County in the May 2009 deaths of his wife, Sheri, and their sons, ages 9 and 11. Their bodies were found in the family's Columbia home.
Coleman has pleaded not guilty.
Prosecutors filed court papers Tuesday that said Sheri Coleman told her friends that her husband had physically abused her and said he wanted a divorce.
Coleman's attorneys argue the texts are inadmissable hearsay.

Prosecutors are seeking the death penalty against Coleman, who once worked as a bodyguard for televangelist Joyce Meyer.
Prosecutors allege that Coleman fabricated threats leading up to the day of the killings to make it look like someone else committed the murders.
Coleman was known to have a mistress in Florida, and prosecutors believe he killed his wife and children to avoid getting a divorce, which would cost him his job with Joyce Meyer Ministries.
