Earlier on Wednesday, police arrested Frank P. Reyos, his girlfriend Brittney Montano and Reyos' sister Jessica Reyos
in connection with Winston's murder.
A probable cause statement alleges that Reyos told a witness that he admitted to killing Kenyatta Winston and dumping his body in a Sugarhouse field sometime before August 29, when Winston's body was discovered
Winston was last seen alive on August 26, getting into a silver 2010 Dodge Nitro.
The statement said that police had probable cause to arrest Reyos for questioning in the murder of Winston, and that investigators were led to the owner of a silver 2010 Dodge Nitro named Jessica Reyos.
During questioning, Frank's sister Jessica admitted to loaning the Dodge to a man named "D" but refused to identify or lead investigators to him for fear of retaliation.
Jessica Reyos was arrested and booked into jail on suspicion of Obstruction of Justice.
The PC statement also said that blood evidence connected to the death of Winston was also found inside the Dodge.
On Tuesday, police spotted a green Honda belonging to Reyos' girlfriend Brittney Montano at the American Best Inn and Suites on 1009 South Main Street in Salt Lake City. The PC statement said that officers saw Brittney Montano approach the car and then returned to a hotel room, where she alerted Reyos that police were observing them.
The document said that Reyos and Montano then got into the Honda and sped away, at one time ramming a police vehicle during their escape.
During the chase, the Honda crashed and both suspects were arrested.
