Danish police have issued an international arrest warrant for a 34-year-old American from Philadelphia in connection with the killing of a Dane whose dismembered body was found in Copenhagen (search) over Easter, police said Monday.

Jared Heller (search) was suspected of being an accessory to murder, said Deputy Chief Superintendent Magnus Andreasen of Copenhagen police. "We have been in contact with the U.S. authorities," he said.

On March 26, two legs and an arm were discovered in a container. Two days later, the rest of the body — in three parts — was discovered in an alleyway a few hundred meters away.

The body was identified as Torben Vagn Knudsen (search), a 41-year-old taxi driver.

A 27-year-old man from Sudan, whom police have identified only with his underworld nickname, "The Jaguar," is also being sought.

The two suspects are believed to have been involved in Knudsen's murder, Andreasen said, adding "we don't know yet who did what."

Heller is married to a Danish woman but the couple no longer live together, Andreasen said. He said Heller has been living in several European countries in recent years but returned to Copenhagen a month ago.

Knudsen was last seen leaving a Copenhagen bar early in the morning on March 27. Witnesses told police that he appeared drunk when he left the bar.

Police released a picture of Heller and the Sudanese man on their Web site.
