Psychologist and Christian broadcaster James Dobson won't be selling videotaped copies of his interview with serial killer Ted Bundy - but he will distribute them and ask for donations.

Dobson, who planned to feature the interview on his half-hour radio broadcast Thursday and Friday, will offer the 29-minute videotape for a suggested donation of "something under $30," according to Paul Hetrick, a vice president for Dobson's Focus on the Family organization.A person who asks for a videotape without enclosing the suggested donation may or may not get a tape, Hetrick said. Because of Internal Revenue Service regulations, the California-based ministry can't sell the tape.

"If someone asked for it, but couldn't pay, we'd probably send it if we were sure it wasn't going to be misused," Hetrick said. "We're not going to send it out all over the place for free. We can't afford to do that."

Bundy confessed to the murders of 23 girls and women - including 11 in Washington state - in the days shortly before he was executed for the February 1978 murder of his last victim, 12-year-old Kimberly Leach of Lake City. Investigators have said he may have killed as many as 100.
