SEYMOUR — A Seymour man is behind bars following a multi-agency narcotics investigation that uncovered a dangerous “mobile” methamphetamine lab and a distribution network spanning two Indiana counties.
The investigation, led by the North Vernon Police Department (NVPD) Narcotics Task Force, culminated on Wednesday, February 4, 2026, when authorities executed a search warrant at a residence in Seymour.
The case began in North Vernon on North Buckeye Street, where detectives discovered more than 10 grams of methamphetamine along with evidence of drug paraphernalia. Most concerning to investigators was the discovery of components for a “mobile” meth lab—a portable setup used to manufacture the drug on the go.
The evidence in North Vernon provided the probable cause needed for a search warrant at a home in Seymour. The raid was a massive collaborative effort involving the North Vernon Police Department, the Jennings County Sheriff’s Office, including the canine unit, the Seymour Police Department, the Indiana State Police, and the specialized ISP Meth Lab Team.
Police arrested Tristan Lemarr, 27, of Seymour, at the scene. Lemarr was transported to the Jennings County Jail and faces several preliminary felony charges, including dealing meth, manufacturing meth, possession of meth, possession of marijuana, and possession of drug paraphernalia.
According to jail records, Lemarr is being held on a $10,055 bond.
Task Force Commander Graham Heffelfinger highlighted the extreme risks associated with mobile labs, which often use volatile chemicals in unstable environments.
“Mobile methamphetamine labs are extremely dangerous, not only to those involved in their operation, but to surrounding residents and first responders due to the risk of toxic exposure, fire, and explosion,” Heffelfinger stated.
He praised the expertise of Trooper Ayers of the State Police Meth Lab Team for safely dismantling the site and mitigating the threat to the neighborhood.
The public is reminded that meth labs produce toxic waste. If you suspect a clandestine lab in your area, do not approach it—contact local law enforcement immediately.
Those facing criminal charges are considered innocent until proven guilty through a fair and due legal process. Accusations alone do not imply guilt; the judicial system will evaluate the presented evidence to reach a verdict.
