A 37-year-old man has been arrested in connection with fatally stabbing a man Sunday night in a small park in Northwest Washington’s Truxton Circle, according to D.C. police.

Deon Anthony Thomas, of Northeast, was charged with second-degree murder while armed. The victim, John Thomas Tillman, 63, of Southeast, died at an area hospital shortly after he was stabbed about 10:10 p.m. at Florida Avenue and North Capitol Street Northwest.

Police have not released a suspected motive in the attack. Thomas could make his first appearance in D.C. Superior Court on Tuesday, when more details will be made available in court documents.

The killing was the District’s third over the weekend and the second in Truxton Circle, a small neighborhood roughly bordered by New York, New Jersey and Florida avenues, and North Capitol Street. On Saturday, D.C. police said a 32-year-old man was found fatally shot in an alley off the 200 block of Bates Street Northwest.

Police said it does not appear the two deaths are related, but were the results of separate disputes. The neighborhood has seen an increase in violence. On Nov. 27, a clerk of a neighborhood store was shot through the neck during an apparent robbery.

In October, two men were shot, one fatally, at a gas station at Florida Avenue and North Capitol Street. Police arrested two suspects in that case and charged them with second degree murder. The gas station is across the street from the park where police said Tillman was stabbed Sunday night.

There have been 102 killings in the District so far this year, compared to 88 in all of last year.
