The hunt for the killer of a 28-year-old man who was shot in his car two blocks from his Capitol Hill rowhouse early Monday continued a day later with little new information. A police report made public Tuesday did reveal one new detail, however: Jason Anthony Emma’s black Audi was still running when police officers arrived to find him dead in the driver’s seat.

Authorities have not said whether they believe Emma, an accountant who worked out of his home, was killed in a robbery or targeted for another reason. A close friend and roommate said he thinks Emma was shot moments after parking his car after a night out and returning to his home the 1200 block of C Street NE a few minutes after 2 a.m.

The police report gave no new clues on the case, adding only fractionally to the scant description of suspects previously distributed by police — two men, one wearing a white T-shirt with dark sleeves.

In the report, police added that both men are between 5-feet-10 inches and 6 feet tall, and weigh between 200 and 220 pounds. The report does not say the source of the descriptions.

On Monday, D.C. Police Cmdr. George Kucik pleaded for help from the public and authorities announced a reward up to $25,000 for tips leading to an arrest and conviction.

Police did not respond to requests for updates in the investigation Tuesday. Emma’s relatives and friends of Emma also did not return calls and e-mails.

One of Emma’s closest friends told The Post on Monday that the victim had just moved into the rowhouse Dec. 1, joining lifelong friends from Virginia. The roommate said Emma, an Arlington native, had been excited about moving to Capitol Hill to join a neighborhood in which residents cared for the city’s future.

Emma’s brother runs a food delivery business; his father is a psychiatrist who lives in North Arlington.

An outpouring of support was evident on Facebook Tuesday, with more than three dozen friends and acquaintances sharing condolences. “My heart is aching for you and your family,” one wrote. “Know that Jason is in a better place, far from this horrendous earth.”
