Mother says her son was paid drugs for baby-sitting for couple investigated in Alexis Rasmussen's death

"(They) continually stated it wasn't their fault since it was not their responsibly to stop Alexis from leaving," according to the warrant.

Over the course of several interviews with Dea Millerberg, police noted that she felt officers were "badgering" her and that she appeared to be "exhibiting signs and symptoms of possible stimulant use, as she had uncontrollable movements during our conversations."

The search warrant attempts to put together a timeline of events of Alexis' activities right before she went missing.

The warrants also paint a picture of Alexis caught up in a world of drug use. Her friends told investigators, though not confirmed by police, that Alexis was often paid with Xanax for baby-sitting, the warrant states.

"In the months leading up to the disappearance of Alexis she was heavily involved in narcotic use, specifically methamphetamine and prescription medication."

It was previously reported that Alexis went to Walgreens in Layton with Dea Millberg on the night she disappeared. According to the warrant, Alexis went with Dea to help complete a drug deal with Alexis' best friend.

On the night she disappeared, Alexis and Dea Millerberg sold Percocet pills to Alexis' friend for $100 and a small amount of marijuana. The surveillance video of Alexis at Walgreens was taken after she allegedly picked up the money from her friend.

"(It was) possibly the second or third time making these arrangements with Dea Millerberg through Alexis' best friend," the warrant states.

Another informant described a kind of crash pad at the Millerberg house. The person said Eric Millerberg would talk about two 16-year-old girls who hung out there and one wanted to be "shot with narcotics and he stated he eventually did that for her."

After Dea Millerberg was arrested and sent to the Weber County Jail, she allegedly made comments to an inmate that were relayed to police.

The inmate told investigators that Millerberg had said, "Something bad has happened and that she, Dea, wants it to blow over and go away. (Redacted) stated "Rooster" has got her caught up in something and she doesn't know what to do," according to the warrant. "Rooster" is Eric Millerberg's moniker.

The staff at the Weber County Jail also later turned a letter over to investigators. The author's name was redacted from the search warrant.

In it, the writer makes statements such as, "It was a terrible tragedy that happened at her home … It's something she (Dea) can't fix. (Redacted) stated (Dea) is worried about telling on her husband (and) it had something to do with a girl dying," the court records state. "Only her, her husband and one other person know about it."

Other statements from the author of the letter included, "She's sorry it happened," "She's protecting herself and husband and one other male friend," "drug related something to do with a case," "Find the car you find an answer, she'd dead" and "Dea knows everything that happened the girl is buried somewhere in the state she's not gone but not alive."

Prosecutors have said they were waiting on complete autopsy results, including toxicology tests, before filing charges in the case.
