MARQUETTE, MICHIGAN – U.S. Attorney for the Western District of Michigan Timothy VerHey announced that Brent Alan Tompkins, 52, of Traverse City, was indicted on charges alleging that he impersonated a federal officer, unlawfully used Coast Guard insignia, and discharged sewage into Lake Michigan. The indictment, announced on August 21, 2026, follows a two-year investigation by the Coast Guard Investigative Service (CGIS) and Michigan Department of Natural Resources Environmental Investigations Section (EIS) for the Michigan Department of Environment, Great Lakes, and Energy (EGLE) into allegations that Tompkins discharged pollutants into Lake Michigan at White Shoal Light. Investigators also identified allegations that Tompkins operated a vessel with insignia resembling U.S. Coast Guard insignia and represented himself as a Coast Guard member to a distressed mariner in Emmet County.
U.S. Attorney VerHey said, “Reports that Tomkins was polluting Lake Michigan got our attention right away because protecting this national resource is a high priority for my office. I appreciate the investigative work that CGIS and EGLE did in this case to make it possible to bring charges. The charges relating to impersonating a Coast Guard officer point to another troubling issue encountered in this case. The public has a right to know when they are dealing with a properly trained public official--and when they are not--especially during a potentially dangerous situation on the water. This is no place for impersonators and wannabes.”
“Protecting the public’s trust in the U.S. Coast Guard and safeguarding our nation’s waterways is critical,” said Assistant Director Joshua Packer of the Coast Guard Investigative Service, LANT Operations. “Impersonating Coast Guard personnel and misusing Coast Guard markings can create serious safety and security risks on the water. CGIS will continue working with our federal, state, and local partners to investigate conduct that threatens public confidence, maritime safety, and the marine environment.”
Tompkins is with false impersonation of a federal officer, in violation of 18 U.S.C. § 912; unauthorized use of a Coast Guard insignia, in violation of 14 U.S.C. § 933; and discharge of a pollutant into a navigable waterway, in violation of 33 U.S.C. §§ 1311(a), 1319(c)(2)(A). The case was investigated by CGIS and EGLE and is being prosecuted by the U.S. Attorney’s Office for the Western District of Michigan. If convicted, Tompkins faces up to 3 years in prison and a fine of at least $5,000 per day for each day of the alleged violation. This case remains pending, and no determination of guilt has been made.
This site models an investigative reporter rather than a wire desk. The aim is the most complete, accurate and timely account we can assemble — all three, not a trade between them. Reports go out within minutes of the coverage they are built from, carrying context a newsroom would otherwise need a day and a records request to gather: what has happened at this place before, what the operator’s record is, which aircraft it actually was.
Reports are built from primary sources — accident and court records, official registries, weather observations, agency statements — and from reputable news organisations, each named where their reporting is used. Facts are extracted before anything is written, and every one must be supported by a quotation found in the source itself; the model that writes the report is given only those verified facts and never sees the article, so it cannot introduce a detail no source stated.
Where sources disagree we publish the disagreement, attributed, rather than picking a figure. Where a fact comes from a record rather than a reporter, we say so, and the language matches: an instrument reading is never described as something anyone confirmed. Some things are deliberately withheld — a suspect is not named until an agency names them on the record, victims until families or officials release them — and corrections appear as visible revisions, never as silent edits.
None of that makes a report true. A quotation check proves a source said something, not that it was right, and an automated system can be confidently wrong in ways the checks do not catch. If something here is wrong, the feedback above is how it gets found. The full methodology, including what we refuse to publish.
