Authorities are asking for the public’s help to locate four Hells Angels wanted in connection with the 2007 kidnapping and robbery of one of their members in El Cajon.

The suspects are David Dabbs, 41, Dustin Harroun, 30, Stephen Sanders, 42, and Troy Scholder, 30.

The four were among other members or associates being sought during an Aug. 3 raid on the Hells Angels Dago clubhouse, authorities said. U.S. Drug Enforcement Administration agents, assisted by the El Cajon SWAT team and San Diego police officers, burst into the fortified clubhouse on El Cajon Boulevard at 5:45 a.m., but no one was inside.

The four men are wanted in connection with the kidnapping, torture, assault and robbery of a patched member who had informed the club that he wanted out, according to arrest warrants filed at San Diego Superior Court.

Three others have also been arrested and charged in connection with the case. A preliminary hearing has been set for Oct. 28.

Investigators have declined to speak about the case, although court records provide a glimpse into the brutal code of loyalty that has often defined the notorious motorcycle gang.

A week before the attack, the victim had gotten into a fistfight with Sanders, the club’s then-president, according to the warrant.

Then on April 26, 2007, the victim told the club at the gang’s weekly meeting, called “church,” that he wanted to leave the club, the court documents state. The full-fledged members voted that the victim would depart in “bad-standing,” rather than “good-standing.”

The victim was beaten and forced to sit still while Dabbs allegedly tattooed over all of the victim’s Hells Angels tattoos, which ran up both sides and the front of his neck and both arms.

The victim was thrown into a pickup and driven to a friend’s house, where he was forced to sign over the title of his motorcycle to the club. He was then driven to his Bay Park apartment to surrender all of his Hells Angels paraphernalia, as well as a 42-inch flat screen television.

His 1999 Harley Davidson motorcycle, which was at a shop getting repairs, was later turned over to an unknown person. Another Hells Angel was found in possession of the bike in 2008; he claimed that he bought it from the victim.

Sanders is also wanted in connection with an unrelated attack on a motorcyclist on May 5, 2010.

The victim, who was friendly with the Hells Angels and another motorcycle gang, the Wrecking Machine, but not himself a member, was beaten with a baseball bat and assaulted by other gang members, according to court documents.

The attack occurred in the parking lot of the San Diego Custom Cycle near the Sports Arena, which was co-owned by Sanders’ wife. One of the alleged assailants, Hells Angel Kirtith Nielsen, was angry because the victim was receiving sexually explicit text messages from his ex-girlfriend, the records state.

The victim was taken to a hospital and treated for facial fractures, and his motorcycle went missing.

Sanders allegedly shipped the bike to Honolulu to be picked up by the president of the Wrecking Machine chapter there. About six months later, the bike was shipped back to San Diego and left on the front lawn of the victim’s old address.

Police later impounded the bike for evidence.

Sanders’ son, Shane, 23, who was president of the local Wrecking Machine chapter, has been charged in the assault, as well as Nielsen, 26.
