Plymouth Police Officer Tristan Allen took a report of a theft from a vehicle on October 14th.
During the officer’s investigation, three male suspects were identified and admitted to stealing the firearm. The suspects were 19-year-old Keegan Burt of Knox, 19-year-old Andrew Quinn of Plymouth, and a 16-year-old unnamed juvenile. Burt and Quinn were both booked into the Marshall County Jail for theft.
Recently, the suspects showed Detective Derek Workman with the Plymouth Police Department the location where they had thrown the handgun into the Yellow River. It was near the walking bridge on the east side of River Park Square.
Detective Workman contacted the St. Joseph County Dive Team, and they agreed to come attempt to retrieve the handgun from the river. This morning (10/24/25), several members of the St. Joseph County Dive Team dove the river and located the stolen handgun. No other items of note were located; however, the Dive Team removed several items from the river.
The handgun located was not suspected to be used in any other crimes and was taken to the Plymouth Police Department for Processing.

Readers are reminded that charging information supported by an affidavit of probable cause is merely an allegation that a crime has been committed, and that there is only probable cause to believe it has. They are presumed innocent throughout the proceedings and are entitled to be represented by counsel and entitled to a trial by jury at which the State is obligated to provide proof beyond a reasonable doubt before a judgment of guilt may be made.
