A traffic violation in Fulton County Tuesday evening led Indiana State Police to a large meth bust. 

Around 5:40 p.m., officers pulled over a pickup truck on U.S. 31 near Fulton County Road 375 North for unsafe lane movement. 

While officers were speaking with the driver, officers noticed indicators of criminal activity. 

With the help of K-9 Hunter, officers found four grams of meth and more than $10,500 in cash. 

Further investigation led officers to a home at 86 Reed Lane in Rochester. 

Once inside, officers found three pounds of meth, about a quarter pound of marijuana, two pounds of methadone pills, 12 rifles, nine handguns and other drug paraphernalia. 

Police also found about $202,628 in cash. 

Sarah Hine, 25, Brandy Fletcher, 42, Stephan Howard, 54, all from Rochester, IN, and William James, 48, Elkhart, IN.

All four were incarcerated in the Fulton County Jail to face preliminary criminal charges for possession of methamphetamine, possession of marijuana, and possession of drug paraphernalia.

Fletcher, Hine, and Howard face additional charges for dealing methamphetamine, dealing in a controlled substance, and maintaining a common nuisance. James faces an additional charge for visiting a common nuisance.
