He was a clean-cut, well-dressed Arizona stockbroker by day. But when he lost the suit and tie, authorities say, Paul Merle Eischeid became one of America’s most dangerous criminals.

Originally from Council Bluffs, Iowa, Eischeid, 36, was a Charles Schwab stockbroker before he joined the Hells Angels motorcycle gang in Phoenix, Ariz.

He is wanted in connection with the savage beating and stabbing death of a Phoenix woman in 2001, a murder believed to have been committed by several members of the notorious gang.

Cynthia Garcia, 44, was intoxicated when she “mouthed off” to some Hells Angels at their clubhouse in Mesa, Ariz., where she would routinely hang out, according to reports. She was assaulted by some members and warned to keep quiet about it. When she refused, she was viciously attacked, beaten and stabbed. The attackers then threw Garcia into the trunk of a car and drove to a remote location of the desert, where they continued to stab the woman as she lay dying.

It was one of the most grisly murders in recent American criminal history, U.S. Marshals service director John F. Clark said of the crime.

Two years later, Eischeid was one of 50 Hells Angels members and associates nabbed in a sweep of motorcycle gang violence in Phoenix. Although he was implicated in Garcia’s kidnapping and murder, a judge allowed him to be released on bail to await trial because he was holding a steady job as a stockbroker and had a relatively clean criminal record, America’s Most Wanted reported.

But after his release, Eischeid somehow removed the tracking device he was ordered to wear, and he fled. He hasn’t been heard from since.

Eischeid is now a fugitive, believed to be roaming the country with help from his Hells Angels cronies. He was added to the Marshals’ list of top 15 most wanted last year.

“He bounces around from location to location wherever there is a [Hells Angels] member that is willing to take him in,” Deputy U.S. Marshal Matt Hershey said.

The U.S. Marshals have not ruled out the possibility that Eischeid is in another country, as his last confirmed sighting places him in Calgary, Canada, last year. Canadian immigration authorities have since issued a warrant for his arrest.

Eischeid blends in easily due to his appearance, which he cares a lot about. He is well groomed, works out often and is rarely seen without clean clothes, according to Hershey. He is extremely talented with finances, and could be working as an online trader.

One conspicuous characteristic of Eischeid’s appearance is his torso, arms and back, which are covered in colorful tattoos.

“[His body] is hard to cover up,” Hershey said.

Eischeid, who also goes by the name Jason Daniel, is a white male, 5-foot-7 and 190 pounds, with blue eyes and brown hair. His last name is tattooed across his stomach, and “Hell 666 Bound” is on his lower back. He may be wearing glasses.

The U.S. Marshals have offered a $25,000 reward for information leading to Eischeid’s capture. Anyone with information on his whereabouts is asked to call the U.S. Marshals at 1-800-336-0102.
