After following up on a tip about marijuana growing on public property near Petoskey, the Michigan State Police reported that its troopers seized 30 such plants from that location on Monday. State police said troopers from the Gaylord post received a tip Monday about an outdoor marijuana growing operation hidden off a walking trail, on public property in Emmet County’s Bear Creek Township. The witness who called it in had seen a man walking around in the area tending to some plants, and after further investigation noticed it was marijuana growing in pots and contacted law enforcement, according to state police Lt. Derrick Carroll. The troopers made contact with the individual and, through investigation, concluded he was the suspect. “Upon interviewing him (suspect) and doing some search warrants, they (troopers) determined he was the suspect,” Carroll said. “They recovered fertilizer and other equipment that this person was using to grow these plants outdoors.” Uniformed troopers seized 30 marijuana plants, not yet mature, from the outdoor operation. According to Carroll, this is the largest quantity of the plants which Gaylord-based troopers have seized this year. The officers also confiscated fertilizer, magnesium and a vehicle that had been used to grow the marijuana.
