Chief deems Hannibal murder suspects 'evil'

Hannibal Police Department chief Lyndell Davis announcement at a press conference Wednesday morning

Two Hannibal men are charged in the Tuesday morning shooting death of a sales clerk at a Hannibal gas station.

Gary J. Wiltermood III, 22, and Michael Studer, 30, both of Hannibal are charged with second-degree murder in the incident that took place at the Abel's Quick Shop at 100 Shinn Lane, Hannibal Police Department chief Lyndell Davis announced at a press conference Wednesday morning.

Adrienne Arnett, 61, of Hannibal was found dead at the at the gas station shortly after 3 a.m., according to the Hannibal Police Department. The Marion County Coroner pronounced her dead at 3:45 a.m.

Both men are being held on $500,000 bond at the Marion County Jail.

Chief Lyndell Davis called the motivation of the crime "evil."

"She was known by officers and by people throughout the community as a very sweet lady who didn't deserve what she got," Davis said.

The men were unable to crack the cash register but managed to steal lottery ticket and cigarettes, Davis said.

The shooter's face was covered during the shooting, Davis said. Evidence gathered after their arrest revealed that Studer was the shooter, Davis said. He would not specify what led investigators to reach that conclusion.

HPD detectives made a series of arrests of people involved in the incident, according to a press release from Lt. John Zerbonia released Tuesday. The arrests began shortly after the incident took place and continued through Tuesday afternoon.

Studer was scheduled for an Oct. 11 court hearing in a case that charged him with failure to pay child support.

Court records show he also had at least three orders of protection filed against him since June 2012 related to abuse, stalking and the child protection act.

Studer's criminal history also includes two incidents that involved violence.

He received a suspended sentence and was allowed to remain free of jail after his Feb. 8 plea to charges of third-degree assault and misdemeanor property damage charges.

He pleaded guilty June 18, 2012 to domestic assault and marijuana possession. He received a 90-day jail sentence on those charges.

Wiltermood also has a criminal history that extends to various counties throughout Missouri and Illinois.

On May 24, 2009 Wiltermood was charged with a felony escape and misdemeanor counts of criminal damage to property and criminal trespass to property in Schuyler County. Records show that he pleaded guilty to that charge and was sentenced to three years in prison.

Wiltermood was arrested March 12, 2011 on charges of failing to register as a child sex offender and possession of a controlled substance after a traffic stop in Macomb. Police found nine pills, including Adderol, inside the car.

The original police report said that Wiltermood registered as a homeless sex offender before moving to the Schuyler County town of Huntsville.

The sex offender charge was eventually dropped, but Wiltermood was convicted May 25, 2011 on the possession charge. He received a one-year state prison sentence, according to the McDonough County Circuit Clerk's Office.

He was also charged in a June 17 incident after a

car crashed into the Papa John's restaurant

at the Steamboat Shopping Center in Hannibal. Police arrested Wiltermood on charges of leaving the scene of a motor vehicle accident, driving while intoxicated, reckless driving and resisting or interfering with an arrest.
