Retirement: His first retirement, highly unexpected, was announced on October 13, 1998. Bell: I told you that there was an event, a threatening terrible event occurred to my family, which I could not tell you about. Because of that event, and a succession of other events, what you're listening to right now is my final broadcast on the air.
Return: He returned on October 28, 1998, leading many to believe it was merely a publicity stunt. Bell asserted that the brief departure was brought on by threats made against his family. On May 29, 1999, Art Bell explained that this retirement was due to an allegation made by hosts of WWCR shortwave radio that Bell had paid to cover up a criminal indictment. (Announcement date from "The Washington Post" 5-29-99, where Bell's show was said to be on 460 stations.)
The actual facts of the matter became public knowledge with Art Bell's second retirement in 2000, when it was revealed that an actual criminal indictment was filed against a person who had assaulted a member of Bell's family. Due to the nature of the crime, Bell had wanted to keep the matter private. The hosts at WWCR shortwave radio had accused Bell of the crime. (Bell took legal action against the hosts and stations, which was settled in 2000.[11])
Retirement: On April 1, 2000, Bell once again announced to his audience his retirement, which would occur on April 26, 2000 (that from "The Washington Post" 4-1-00), but he offered no details other than expressing intentions to "resolve a family crisis." On April 11, 2000, Mike Siegel was introduced as the new host of Coast To Coast AM. On April 27, 2000, Siegel took over the program which at the this time had an estimated 22 million listeners. (That from "The Seattle Times" 4-12-00.) It was later explained he had left to deal with the aftermath of a sexual assault against his son. Brian Lepley, a substitute teacher, was convicted of sexual assault and attempted transmission of HIV and was sentenced to 10 to 25 years.[12]
Return: On January 24, 2001, it was announced (in Vancouver, Washington's "The Columbian" newspaper), Art Bell would return to Coast To Coast AM on February 5, 2001. Bell noted that since his departure the show had lost a number of affiliates, commercial content had risen to an unbearable level, and Siegel had taken the program in a "different direction" of which Bell disapproved. He retained some authority over the program as its creator and thus felt his return was necessary.
