Dover Police detectives have questioned Shamarr Willingham of Dover in connection with a fatal shooting incident Sunday afternoon.

Willingham, 32, came in to Dover Police headquarters late Monday afternoon with several other people, evidence regarding the shooting and an attorney, said police spokesman Cpl. Mark Hoffman.

“He was completely cooperative with us and very open,” Hoffman said. “He explained to us what happened.”

Hoffman said he could not go into details about what Willingham told detectives investigating the shooting of Yusif Lamb, 33, of Montclair, N.J., nor could he confirm Willingham had claimed self-defense in the incident.

Police say they do know the two men had a confrontation in the first block of South Kirkwood Street and that Willingham fired several shots at Lamb, one of which struck Lamb in the chest. Lamb later died at Bayhealth-Kent General Hospital.

The driver of a red Jeep Commander, in which Lamb is thought to have been riding, was seen leaving the area; the owner of that vehicle later contacted police and it has been impounded as evidence.

Hoffman said a decision on how to proceed will be made later Aug. 26 after police consult with the state attorney general’s office.

Willingham was released by police following their questioning and has not been formally charged with any crime, Hoffman said. He was wanted for reckless endangering and possession of a firearm during commission of a felony.

“The decision was made not to charge him at this time,” Hoffman said. “We know where he is and we have no reason to believe he is a flight risk at this point.”
