Three people involved in an incident that resulted in multiple people being stabbed at a Halloween party in Sandy have been rounded up and charged in 3rd District Court.

Four people were stabbed at a party Oct. 27 near 9900 South and 1300 East. Two were sent to the hospital in critical condition, while two others were treated and released with minor injuries.

Valdez, 28, was charged in 3rd District Court with aggravated robbery, a first-degree felony; attempted homicide and aggravated assault, both second-degree felonies; and possession of a dangerous weapon, a third-degree felony.

On Tuesday, Tevita Tafuna, 25, was arrested and charged in 3rd District Court with aggravated robbery and possession of a dangerous weapon. Tafuna was also on federal probation at the time. When he went in for a scheduled check-in with his probation officer, investigators arrested him, said Sandy Police Sgt. Victor Quezada.

Rochelle Linda Noble, 26, was arrested Thursday night at an apartment. She was charged in 3rd District Court with aggravated assault, a third-degree felony.

All suspects were arrested without incident.
