An Aurora police officer has been arrested on suspicion of multiple felonies, including attempts to influence a public servant and tampering with physical evidence.

A warrant for the arrest of Matthew A. Ewert, a seven-year veteran with Aurora, was issued Monday in Boulder County, according to court records.

Ewert, 34, who was arrested by Erie police, has been placed on unpaid administrative leave, according to the Aurora police department.

The case centers around a juvenile, a nephew of Ewert’s, who allegedly threatened another juvenile with a Glock handgun loaded with hollow point bullets on July 1, according to an arrest affidavit.

According to the affidavit, three teenage boys met near Perry Street and Huntley Creek Court in Erie where they planned to smoke either methamphetamine or crack cocaine beneath a bridge. At one point, the gun was cocked and pointed at a victim.

A victim also was hit over the head with a can of Axe body spray and then hit in the nose with the can. The Axe was sprayed into the victim’s face.

As Erie police investigated the gun and assault incident, Ewert allegedly became involved in the case, using his status as an Aurora police officer to obtain reports, the affidavit said.

The juvenile suspect told Erie police that the Glock belonged to his grandfather.

When Erie police got a search warrant to seize the gun as evidence, it was in a safe in Ewert’s garage. Investigators were initially looking for the gun in another safe, but it had been moved.

Ewert told an Erie investigator he would allow them to serve the warrant and take the gun, but said he was “doing this under duress.” The gun was seized on Friday July 7.

Ewert told the investigator that he had removed the hollow-point bullets from the gun, and placed them in a plastic tub with other hollow-point bullets, which were also in the safe.

“The ammunition in his gun safe and the ammunition that was previously in the gun was duty ammunition provided to him by the Aurora Police Department,” according to the affidavit.

Ewert’s bond was set at $5,000. He was ordered not to contact the juveniles in the case — or their families.

Aurora police will conduct a separate internal investigation after the criminal investigation is completed.
