OTTUMWA — On Tuesday, Ottumwa police said potential evidence was found when they stopped Preston Martin in connection with a weekend death. Court documents available Wednesday morning show what it was.

Martin, 37, is charged with first degree murder in the weekend death of Thomas Foster. Police first went to Foster’s neighborhood in the 500 block of Queen Anne Avenue Saturday morning after a report of a suspicious person. After Foster was found, that description was rebroadcast, and eventually led to Martin.

The criminal complaint filed in Martin’s case shows that initial call about a suspicious person was made by Foster. When officers stopped Martin, “a dried substance consistent in appearance with blood was observed on [Martin’s] boot.”

Martin had also been exchanging coins from a container for cash at convenience stores, police said in the complaint. That container and the money is believed to have come from Foster’s home.

Court records show Martin pleaded not guilty. A preliminary hearing is scheduled for June 3. Martin is being held in the Wapello County Jail on $1 million cash only bond.
