A 27-year-old Provo man admitted Monday that he made terroristic threats to police last month in the wake of a fatal officer-involved shooting.

Michael Leon Angus pleaded guilty Monday to second-degree felony terroristic threats, according to 4th District Court records.

He faces up to 15 years in prison when sentenced on May 4, but plea agreement documents indicate that prosecutors will ask that he not be sent to prison. The agreement also indicates that the charge will be reduced by two steps if he successfully completes probation.

Angus admitted in court records that he wrote "terrorist threats" on social media directed at the Provo Police Department after the Feb. 15 shooting of Cody Evans, who was killed after brandishing an Airsoft replica of an AR-15 rifle at police.

Evans, 24, was killed by police following a domestic violence report to police from his estranged wife.

The same day, several "alarmed" citizens called Provo police alerting them that Angus had posted threats against officers on his social media page, including that he would retaliate with high-caliber guns and C-4 explosive, according to court documents.

Angus allegedly posted: "To provo pd. Beware of c4 and date 50cal bitches. Im fed up yall killin my homies, im killing u! Rip cody, i love u homie."

While conversing online with at least one other person, Angus also allegedly posted; "Ima kill all u provo cops ... Anyone whos down to ride on these pigs lemme know asap. if not ill do it alone."

Charging documents note that C-4 has the capability of causing mass casualties.

A probable cause statement filed with the court indicates that the threats "caused fear and alarm" to residents and police officers in Utah County, "who have remained on very high alert for the past six days ..."

The statement also says that multiple police agencies in Utah County used "a large amount of manpower and resources ... to deal with the possibilities of these threats being carried out."
