(KMOV) -- Chris Coleman filed a motion on Friday to have his triple murder conviction thrown out, citing violations of the United States Constitution among other reasons.
Coleman was convicted May 5, 2011, in the strangulation deaths of Sheri, Garrett, and Gavin Coleman that took place in May of 2009.
Coleman’s attorneys claim 15 errors in the case, many of which are objections raised either before or during the trial. Attorney Jim Stern says allowing a forensic linguistic analyst to testify that Coleman’s known writings were linguistically similar to paint messages left at the crime scene was testimony that “has never been allowed in a criminal case in Illinois.”
Another point of contention will be the hearsay statements allowed at trial. Friends of Sheri Coleman testified that Sheri told them Chris wanted a divorce. The motion claims “such statements have never been allowed by the Illinois Courts to sustain a conviction,” and that those statements were a violation of the Fifth and Sixth Amendments to the United States Constitution.
Coleman also claims a mistrial should have been declared when the jury declared itself “hung” during deliberations. Judge Milton Wharton will have to rule on the motion for a new trial.
