Police are searching for a man suspected in the burglary of a Union convenience store and several homes, who led officers on an extensive foot pursuit Thursday.

Justin V. Mitchalk, 21, of Robertsville, is wanted in connection to the early morning break-in of the North Side Quick Stop on North Washington Avenue.

A second suspect, Jacob Donius, 20, of Edgar Springs, was arrested after fleeing on foot from police Thursday afternoon. He was carrying a stolen semiautomatic pistol.

According to Union Police Chief Norman Brune, Mitchalk and Donius forced open a door on the north side of the store at 4:23 a.m. There were wood fragments and the door strike plate on the floor of the store.

Police were alerted by a security alarm, but did not find any suspects when officers arrived on the scene. There was no merchandise or contents taken from the store, police said.

Once the owner of the store arrived on the scene, officers reviewed surveillance footage that showed one suspect holding a cloth over one camera as the other suspect forced the door open. The alarm was activated and the suspects fled on foot from the store, Union police said.

Detectives identified the suspects utilizing the surveillance footage, and located the men at a 4:20 p.m. at a home in the 600 block of North Washington Avenue.

When officers arrived at the home, Mitchalk and Donius fled on foot in the direction of the Union Splash-N-Swimplex.

Officers nabbed Donius, who was wanted on a probation violation. In 2010, he was charged in St. Charles County with sexual misconduct involving a child under the age of 15, according to court records. Donius was sentenced to five years’ probation.

Mitchalk eluded Union Police and Franklin County deputies following an extensive foot chase in the northern parts of Union between Potomac Court and Independence Drive.

During the pursuit, some businesses were on lock down, witnesses said.

Between 2010 and 2012, Mitchalk had been charged with burglary, stealing, receiving stolen property and property damage.

Police recovered a backpack that Donius was carrying containing items stolen from homes in Union, including the semiautomatic pistol Smith and Wesson pistol stolen from a safe in the garage of a Hickory Circle home late Wednesday or early Thursday.

The suspects allegedly broke into a second Hickory Circle home.

Police also recovered items from a Wednesday night burglary on Heard Court where suspects allegedly broke into the home through a window and stole prescription medication, cash, cigarettes and the key to a Chevrolet Trailblazer. There also were cigarettes stolen from the vehicle, police said.

Police will seek felony charges against Mitchalk and Donius, including burglary, property damage and resisting arrest.

If anyone has any information on the location of Mitchalk, they can contact Union police at 636-583-3700, or the Franklin County Sheriff’s office at 636-583-3596.
