KENTWOOD, MI - A man who used to send people to face a judge can't seem to keep away from court himself.

Twice convicted sex offender and former sergeant for the Kent County Sheriff's Department Matthew Lavern Guy is charged with being a felon in possession of firearm and ammunition and also for failing to report a new email address to his probation officer as required by the terms of his probation.

In July 2004, Guy was sentenced to 1-1/2 to 10 years in prison for soliciting sex and sending pornographic pictures to what he thought was a 14-year-old boy -- but was actually an undercover cop.

He was out of prison by November of 2006, according to court records, but had to register as a sex offender for 25 years.

In December, 56-year-old Guy was given probation after he pleaded guilty to gross indecency between males for receiving oral sex from a man at the park and ride lot along West River Drive NW near US-131 on June 24.

Guy's newest charges stem from an anonymous tip to police in February about Guy allegedly showing a co-worker pornographic photos on his computer at his current job at a delivery company in Kentwood, according to a probable cause affidavit filed by the Kentwood Police Department.

This led to police contacting Guy, where they allegedly found that he had failed to notify the probation department of a new work-related email address.

Because he has been convicted of computer-related crimes, Guy must let his probation agent know of all his email addresses.

Police then searched Guy's home in Belmont and found a handgun in a case along with ammunition, according to police. As a convicted felon, Guy is not allowed to possess firearms.

Police report that Guy told them he "thought he went through and got rid of all the guns," but he did acknowledge the one in the case.

Guy faces a maximum sentence of five years in prison on these charges.

Guy appeared in Kentwood District Court on Thursday, April 16, where he waived his probable cause hearing, sending the case to Kent County Circuit Court before Judge George Buth.

When sentencing Guy in December, Buth told him he was baffled by the former law enforcement officer's behavior.

"Where you go from here is on your shoulders," Buth told the former cop in December.

The Kent County Prosecutor's Office told Guy that unless he pleads guilty as charged, he could be facing additional charges arising from this investigation.

Guy was a sergeant with 17 years of experience with the sheriff's department in 2004 when he was charged by the Michigan Attorney General's Office following a nine-month investigation that started with an undercover New Jersey police officer posing as a boy.

Investigators say he used a Web cam to send "pornographic photos" over the Internet and tried to solicit the undercover officer for sex.

Guy is a husband and father of two, a graduate of Grandville High School and Grand Valley State University. He worked briefly for the Walker and Grandville police departments before he was hired as a Kent County deputy in 1987.

He is free on a $3,000 bond.
