Police arrested three people Tuesday night, saying they would be charged with the possession of chemicals to manufacture drugs, after finding meth-making materials in a backpack.

Police arrested Steve Colian, 35, Michael Hover Jr., 24, and Sarah Sines, 31, according to the Morning Journal. Salem Police charged all three with obstruction of justice.

“They had most of the necessary chemicals to make meth,” Columbiana County Drug Task Force Director Lt. Brian McLaughlin said.

According to McLaughlin, most of the evidence was found in a backpack, including syringes. He said they got to the three suspects before they started cooking, noting they had an acid gas generator, which can be used to make meth.

McLaughlin said the three would also receive a felony charge of possessing of chemicals to manufacture drugs.

According to Salem Police Department Lt. Charles Shafer, the police office’s dispatch center received a call at 5:14 p.m. to search for a possible stolen car that had been tracked to the 500 block of East Third Street through vehicle communications provider OnStar.

Police said they found the vehicle at an East 3rd St. property in Salem. Police also said they saw someone crawl through a window of a nearby building, then searched the building after they found out that no one was supposed to be inside.

Police reported finding three people at the building with spoons and needles in the garage of the building. While checking inside the garage, police said they found a backpack with possible meth-making materials, then cleared the building and called the Columbiana County Drug Task Force and the Salem Fire Department, according to Shafer.
