Two men were charged with murder in Manhattan on Thursday, a day after the body of a Connecticut man they had partied with over the weekend was found in a shallow grave on the Jersey Shore.

The men, James Rackover, 25, of Manhattan, and Lawrence Dilione, 28, of Jersey City, were charged with second-degree murder, concealment of a human corpse and tampering with physical evidence in the fatal stabbing of Joseph Comunale, 26, of Stamford, Conn. Mr. Dilione was also charged with hindering prosecution. They were awaiting arraignment on Thursday in Manhattan Criminal Court.

Robert K. Boyce, the New York Police Department’s chief of detectives, said investigators recovered 32 pieces of evidence from Mr. Rackover’s blood-spattered apartment at 418 East 59th Street, including sheets, towels and clothing that belonged to Mr. Comunale. The men had tried to clean up the scene with bleach, Chief Boyce said.

The police said Mr. Comunale was stabbed 15 times in Mr. Rackover’s fourth-floor apartment on Sunday, after the three men had met in Greenwich Village on Saturday night. The police did not offer a motive for the killing, and neither suspect was cooperating with the investigation, Chief Boyce said.
