The suspect nabbed in the stabbing murder of a jogger in Washington, DC, is a 23-year-old resident of the capital with a criminal past, police officials said Thursday.

Anthony Crawford was charged with first-degree murder in the death of Wendy Martinez, an avid runner who was engaged to be married just last week.

DC Police Chief Peter Newsham said Crawford, who lives in the northwest area of the city, was picked up Wednesday night at a park at 14th Street NW and Girard Street NW — about a mile and a half away from the attack.

“The suspect did not cooperate with us,” Newsham said. “We don’t have anything that suggests a confrontation between the two. It looks like it was an unprovoked attack.”

Crawford allegedly plunged a knife into Martinez as she jogged westbound on P Street NW at 11th Street around 8 p.m. Tuesday.

Graphic surveillance video shows the 35-year-old tech employee stumbling into a nearby Chinese restaurant, bleeding from the neck and begging patrons for help. Customers, including a nurse, tried to save her — but Martinez died of her injuries at a local hospital.

“Thankfully, there were some folks in the carryout who really went above and beyond to try to help her before police and fire could arrive on scene, but unfortunately, they couldn’t save her life,” said Newsham.

Martinez did not know her attacker before she was murdered and there were no signs of an attempted robbery, he said.

“We don’t have a motive in this case,” Newsham said, adding that investigators are examining Crawford’s criminal record for any clues.

Crawford was treated at the hospital for an injury on his hand.

Tips that poured in after police released images of the suspect — wearing a distinctive T-shirt, sweatpants, white socks and sandals — were key to making an arrest in the case, Newsham said.

He added that the slaying was rare for the city, let alone a neighborhood as safe as Logan Circle.

“This is a very isolated instance,” he said. “You don’t see crimes like this, even in the course of my career.”
