TEMPLE (August 23, 2012)--A Temple man who earlier pleaded guilty to possession with intent to distribute methamphetamine within 1000 feet of a public school campus is headed to federal prison.

Mark Duane Preston was ordered Thursday to serve 72 months in federal prison followed by three years supervised release, and ordered to pay a $1,000 fine and a $100 in special assessment to the court.

Preston was the target of an investigation into the possession and sale of methamphetamine that centered on a house on Midway Drive, across the street from Bonham Middle School.

Temple police officers executed a search warrant at that address and recovered several capsules filled with a brown substance, scales, the cutting agent MSM, a marijuana grinder, baggies with methamphetamine residue, baggies with methamphetamine, paraphernalia and paperwork with Preston's name on it.

Court documents show the substances tested positive for the presence of methamphetamine.

On April 18, 2012, when agents went to the residence to serve the federal arrest warrant, officers located a baggie with a trace amount of methamphetamine, an IPhone with text messages indicating the sale of narcotics and a 20-gauge shotgun.

Officers also seized the shotgun because Preston had been convicted of a prior felony.
