Two men were convicted this week of methamphetamine trafficking in Cobb County, authorities said.

Shortly after the trial for Jamie Lopez-Vasquez began on Tuesday, Martin Munoz-Olveda pleaded guilty to trafficking, prosecutors said.

Then, through an interpreter, Munoz-Olveda testified against the 33-year-old Lopez-Vasquez, authorities said.

Munoz-Olveda, 49, was sentenced to 15 years in prison, followed by 15 years on probation.

On Thursday, the jury hearing Lopez-Vasquez’s trial found him guilty of methamphetamine trafficking and possession. A Cobb County superior court judge sentenced him to 30 years in prison and ordered him to pay a $1 million fine, court officials said.

Lopez-Vasquez, a native of Mexico, also is subject to deportation, authorities said. He was acquitted of methamphetamine manufacturing, prosecutors said.

During the trial, prosecutors showed evidence that Lopez-Vasquez and Munoz-Olveda were among a group living at a so-called “stash” house in the 2400 block of Glendale Circle in Smyrna. Last September, DEA agents and police found 17 pounds of meth with estimated $750,000 street value, authorities said.

A third man, 31-year-old Jorge Alcantar-Alvarado, remains in the Cobb County Adult Detention Center on $55,220 bond, awaiting trial for meth possession and trafficking charges.
