Four people were arrested early Thursday in connection with the operation of a methamphetmine laboratory in a Kearns neighborhood.

Salt Lake County Sheriff's deputies and DEA agents served a warrant at the residence, 4131 W. 5010 South, at 9 a.m., and found a partially dismantled meth lab, Salt Lake County Sheriff's Sgt. Paul Burnett said. Parts of the dismantled lab were found hidden around the house, he said.The names of the four people arrested were not available at press time, but Burnett said three men and one woman were in custody. One of the men is a resident at the house, he said.

Police have been monitoring activities at the home for about five months, since neighbors complained to deputies at the county's west patrol office in Kearns, Burnett said. Last week, officers recovered materials from a trash can that indicated a meth lab might be in operation, Burnett said.

One neighbor, who asked not to be identified, said he was surprised to learn his neighbor was making meth.

"I thought he was selling drugs out of there, because people come and go at all hours, but this is a surprise," he said.

The man said the house is occupied by an elderly woman and her son. The neighborhood is a quiet one filled with nice homes, where most residents are retired, he said.
