Coralville police have arrested a couple after allegedly locating heroin in their residence.

Taisha Kiawana Poole, 27, and Lloyd Calvin Jamerson III, 30, Coralville, were charged Tuesday with controlled-substance violation, endangerment/no injury, and failure to affix a drug-tax stamp.

Complaints said the couple was arrested Sept. 19 after Johnson County Drug Task Force officers executed a warrant on their residence.

Jamerson was allegedly observed and recorded by the task force selling heroin to an undercover member of the task force twice — once on Sept. 12 and again on Sept. 19. The complaint said his children, ages 2, 5, and 7, accompanied him in the car during the alleged Sept. 12 heroin deal.

The complaint said officers located approximately 12 grams of heroin in the apartment freezer, and Jamerson admitted to possessing the heroin.

In total, Jamerson is charged with three Class-C felony controlled-substance violations, each one punishable by up to 10 years in prison and a fine of $50,000.
