The man charged with savagely killing two teenagers and dumping their bodies in a mine has been making a lot of calls from the Utah County Jail — more than 1,000 — and he’s been talking about the homicides.

According to a recently unsealed search warrant, Jerrod Baum has been talking about killing Brelynne “Breezy” Otteson and Riley Powell, despite the fact that each time he uses the phone there’s a warning that the calls are recorded.

Baum, 41, has been charged with two counts of aggravated murder, two counts of aggravated kidnapping, two counts of abuse or desecration of a body, and one count each of obstructing justice and being a felon in possession of a dangerous weapon.

According to charging documents, Baum forced Otteson to kneel before a mine shaft and watch as Baum beat and stabbed her 18-year-old boyfriend before “she had her own throat cut and was also thrown into the open mine" near Eureka. The teenagers disappeared in December; their bodies were found in March.

The warrant states that most of the “over 1,000 calls” were made to an unidentified woman believed to be in Missouri, and that "many specific details were discussed regarding the deaths of Riley Powell and Brelynne Otteson.”

Police, who declined to comment on the ongoing investigation, requested a search warrant for the Facebook account of the woman Baum had been speaking to on the phone.
