Detectives also found marijuana, condoms and a DVD of the 2001 film "Donnie Darko" in the hotel room, according to a new search warrant made public Tuesday.
Joanne Witt's daughter, Tylar, and her boyfriend, Steven Colver, have been charged in the murder. Witt did not approve of the relationship, and was found stabbed to death in her El Dorado Hills home in an upscale gated community 30 miles outside Sacramento.
Prosecutors are also considering whether to charge Tylar Witt as an adult in the stabbing death. Colver pleaded not guilty at a separate hearing Monday and was ordered held without bail.
The two were arrested Wednesday at a strip mall south of San Francisco following a two-day search.
The charges against Tylar Witt are sealed because of her age. But after the hearing, El Dorado County Deputy District Attorney Lisette Suder that the Witt is charged with murder. She is also charged with battery on her mother and receiving stolen property for a May 18 incident at their home.
