SAN DIEGO -- Recently unsealed court documents reveal that videos seized from the home of convicted child killer David Westerfield suggest he was surreptitiously filming his female neighbors through their windows.

One video shows a female neighbor drying off after getting out of the shower.

The unsealed documents also provide a deeper look into Brenda and Damon van Dam's much-scrutinized lifestyle.

The videos provided support to prosecutors who said Westerfield was "a Peeping Tom" who "very likely scouted out the van Dam residence prior to entering."

The information was revealed Thursday when hundreds of pages of legal motions were unsealed, on order of Judge William Mudd, who presided over the Westerfield trial and sentenced him to death last week.

Westerfield was convicted in August of the kidnapping and murder of 7-year-old Danielle van Dam.

According to a pretrial motion filed by prosecutors April 29 and made public Thursday, another video showed Westerfield secretly filming himself involved in sexual relations with a woman who did not appear to know she was being filmed.

The tapes were not made known to the jury because Mudd ruled that they were irrelevant and prejudicial.

The documents unsealed Thursday also contain information about the lifestyle of Danielle's parents. It suggests that Brenda van Dam threatened to leave her husband, Damon, for good if he went forward with a plan to separate so he could further explore the world of swingers.

During the murder trial, the defense had hoped to place more focus on the couple's widely rumored spouse-swapping lifestyle.

Prosecutors fought during pretrial hearings, however, to limit how much of that the jurors would hear.

Brenda van Dam told detectives she and her husband swapped partners with another couple at a 2000 Halloween party. She said they engaged in spouse swapping four other times, then stopped.

More sealed documents from the case are expected to be released on Monday.
