Mathew Irving found guilty

July 1, 2014

Marshall County Courthouse - A jury found Mathew Irving guilty of Murder in the 2nd Degree. The jury trial began on June 24th, 2014.

On July 14th, 2013, the Marshall County Sheriff's Office discovered a deceased female in the back of a parked mini-van just East of Marshalltown. The deceased victim was later identified as 55 year old Rebecca Hall of Marshalltown, Iowa. The Marshall County Sheriff's Office and the Iowa Division of Criminal Investigation (DCI) subsequently initiated an investigation.

Following their investigation, on July 16th, 2013, 40 year old Mathew Irving of Marshalltown was arrested and charged with Murder in the first degree. Irving confessed to DCI Agents and Marshall County Sheriff's Office Deputies that he killed Rebecca Hall as a result of an argument that ensued following a consensual sexual encounter. Mathew Irving stated to police that following the murder, his wife, Shawn Irving, assisted him with destroying evidence that would potentially link him to the crime. During the trial, Defendant Mathew Irving took the stand and testified that the killing was a result of self-defense and an accident.

This case was investigated by the Marshall County Sheriff's Office and the DCI, and prosecuted by the Marshall County Attorney's Office and the Iowa Attorney General's Office. Sentencing for Mathew Irving will be on August 18th, 2014.
