Washington police and Franklin County deputies are involved in a joint investigation of several burglaries that occurred over the last several weeks.

Two adults and two juveniles are suspects in the investigation.

“It’s still unraveling,” Detective Sgt. Steve Sitzes said of the probe.

At this point, police are investigating three burglaries in Washington and two in unincorporated Franklin County, Sitzes said.

One suspect, Tyler J. Thurman, 17, Marthasville, is charged with one count of stealing a firearm. A $25,000 cash-only bond was set in that case.

Franklin County Prosecuting Attorney Bob Parks said he issued the weapons charge in order to hold Thurman while the investigation is ongoing.

Parks said reports have been filed with his office and he is considering what other charges to file.

Sitzes said during questioning Thurman admitted to being involved in three burglaries in Washington. He also admitted to at least one burglary in the county.

The two juvenile suspects are in the custody of juvenile authorities, and detectives have questioned the second adult male suspect but he has not been charged yet.

Franklin County Sheriff Gary Toelke said the county detectives still are working to recover a couple of handguns stolen in burglaries out in the county.

An Apple iPad, two large jars of loose change, including some silver dollars and old coins, and a bottle of vodka were taken in another burglary south of Washington, Toelke said.

A boy, age 4, was walking with his father and found a black powder rifle hidden by the wellhouse on East Ninth Street, Sitzes said.

Other burglaries in Washington occurred at homes on Lancaster Court, Missouri Avenue and Alberta Lane, Sitzes.

The break-ins took place between July 7 and July 17, according to reports.

One handgun recovered was taken in a burglary in the New Haven area.

In one case, suspects broke into a home but didn’t steal any items. They did, however, eat some tilapia that the homeowner had cooked, according to Sitzes.

Investigators are attempting to determine if the suspects were involved in other burglaries.
