An Illinois man whose wife and two sons were found strangled in their bedrooms resigned from his job working as a security guard for a televangelist.

Chris Coleman left his position at Joyce Meyer Ministries after an internal inquiry found he had failed to follow a company policy.

A spokesman for the company, a worldwide television evangelist organization based in Jefferson County, Ill., would not say which policy had been violated.

The latest news comes amid reports that Coleman had met up with a Florida woman described as his girlfriend while on trips for the ministry, a source told the St. Louis Post-Dispatch.

Police reportedly interviewed the girlfriend in Largo, Fla. The woman, believed to be a friend of Coleman's wife Sheri since high school, has not responded to messages, the Post-Dispatch said.

Sheri Coleman and her sons, 11-year-old Garett and 9-year-old Gavin, were found murdered on May 5.

Police have identified a suspect in the murders, but have not disclosed the person's identity as they await further forensic results, a reporter for the Post-Dispatch told FOX News Friday.

Police have not said Coleman is a suspect but have been closely tracking his movements. On Monday, they got a court order to take his fingerprints.

Coleman’s attorney William Margulies says the family isn't commenting.

No charges have been filed.

Investigators working on the case turned over evidence to the prosecutor Wednesday and announced that one lone killer, whose name was not revealed, had been identified.

Detectives said that, as of late Wednesday afternoon, they had stopped their surveillance of Chris Coleman, who has been staying with his parents in Chester, Ill.
