The Sayreville Police Department is investigating a letter sent to the town’s mayor that “gloated” over the death of Council Member Eunice Dwumfour.

The town's business administrator tells News 12 that the letter was racist, but not a threat.

Dwumfour was shot multiple times outside her Sayreville apartment complex on Feb. 1.

“That letter was so heinous that it immediately had to be turned over to authorities. It's been ordered to be processed by forensics to find out where it originally came from,” Sayreville Mayor Victoria Kilpatrick said at an April 10 meeting.

Kilpatrick said that she would not seek re-election as mayor due to threats and heated political rhetoric in town.

“When I tell you that, yeah, there are times I don’t feel safe,” Kilpatrick said at that meeting.

Sayreville officials say that they will conduct a security assessment of town hall.

Dwumfour’s slaying remains unsolved. A motive for the killing was not clear.
