Actor Melissa Gilbert among witnesses at New Mexico detention hearing for husband Timothy Busfield

ALBUQUERQUE, N.M. (AP) - Actor Melissa Gilbert could speak Tuesday at a New Mexico detention hearing for her husband, Emmy Award-winning actor Timothy Busfield, who faces child sex abuse charges stemming from allegations that he inappropriately touched a minor on a TV series set.

Busfield, who is known for appearances in "The West Wing," "Field of Dreams" and "Thirtysomething," was ordered held without bond last week at his first court appearance. Busfield called the allegations lies in a video shared before he turned himself in. Gilbert, who played Laura Ingalls in the 1970s to '80s TV series "Little House on the Prairie," is on the list of potential witness submitted ahead of the hearing.

Albuquerque police issued a warrant for Busfield's arrest earlier this month on two counts of criminal sexual contact of a minor and one count of child abuse. A criminal complaint alleges the acts occurred on the set of the series "The Cleaning Lady," which was directed by Busfield and was filmed in the city.

According to the criminal complaint, an investigator with the police department says the child reported Busfield touched him on private areas over his clothing on one occasion when he was 7 years old and another time when he was 8. The boy's twin brother told authorities he was also touched by Busfield, but did not specify where. He said he didn't say anything because he didn't want to get in trouble.

On Monday, Busfield's attorneys submitted two brief audio recordings of initial police interviews in which the children say Busfield did not touch them in private areas. The attorneys in a court filing argue that the complaint characterizes the interviews as a failure to disclose abuse, but an "unequivocal denial is materially different from a mere absence of disclosure."

According to the criminal complaint, one of the boys disclosed during a therapy session that he was inappropriately touched by the show's director. Those records were obtained by police during the investigation.

Busfield's attorneys have argued that the allegations emerged only after the boys lost their role in the TV show, creating a financial and retaliatory motive. The filings detailed what the attorneys said was a history of fraud by both the boys' father and mother. They cited an investigation by Warner Bros. into the allegations that found the allegations unfounded.

Busfield also submitted letters vouching for his character, and his attorneys say he passed an independent polygraph test.

Legal experts say New Mexico is among a few states that allow polygraph evidence in criminal cases, but a judge has final say over whether one can be used. There are strict requirements for admission.
