Marshalltown man arrested possessing powder and crack cocaine

May 31, 2019

Rural Marshall County, Iowa - Shortly before midnight May 30, 2019, John Demetrus Wallace, age 47, Marshalltown was stopped by a Marshall County Sheriff's deputy and subsequently found to be in possession of powder and crack cocaine.

The Mid-Iowa Drug Task Force (MIDTF) previously served a drug search warrant on Wallace on December 25, 2018. Relatively soon thereafter the MIDTF gained information indicating that wallace was selling cocaine and resumed an investigation, which has been ongoing.

A Marshall County deputy sheriff located Wallace driving on Highway 330 in southern Marshall County and subsequently arrested him for traffic violations. At the time of the stop, approximately 3 ounces of suspected cocaine was thrown from the vehicle.

A search warrant on the vehicle and his residence at 402 Melody Lane Apartment #2, Marshalltown, yielded an additional approximate 14 grams of suspected crack cocaine found concealed the vehicle and a small amount of marijuana and paraphernalia from his residence.

The street value of the cocaine products is estimated at $9200. Wallace was charged with a mix of felony and misdemeanor offenses including: Possession of a schedule II controlled substance with the intent to manufacture or deliver; Failure to affix a drug tax stamp; Possession of marijuana, 3rd or subsequent offense; keeping a vehicle for the purpose of using or selling drugs; keeping premises for the purpose or using or selling drugs; and traffic violations.

Wallace made his initial appearance Friday morning and was held in jail on a $25,000 bond.

This incident was a MIDTF coordinated investigation with the assistance of the Marshall County Sheriff's Office and Marshalltown Police Department. The MIDTF is funded in part by a grant through the U.S. Dept. of Justice, Bureau of Justice Assistance and the Governor's Office of Drug Control Policy.
