Anchorage police said Sunday three more suspects have been arrested in connection to the murder of 19-year-old Cynthia Hoffman near Thunderbird Falls trail last week.

The Anchorage Police Department has arrested 19-year-old Caleb Leyland, one juvenile male and juvenile female. Police say all three were involved in planning the homicide along with 16-year-old Kayden McIntosh and 18-year-old Denali Brehmer, who have also been charged.

Leyland faces charges of first-degree murder and conspiracy to commit murder. Court documents say he admitted to giving Brehmer and McIntosh his Chevrolet Trailblazer to kidnap Hoffman and kill her.

On June 8, detectives found the residence of the juvenile female. Her mother confirmed Leyland and the juvenile suspects were all at the residence. APD officers went to the home and took all three suspects in for questioning.

Leyland and the juvenile male admitted their involvement and agreed, along with McIntosh and Brehmer, to kidnap and murder Hoffman, the complaint says.

The juvenile female said she was present at the time the crimes were planned.

The two juvenile suspects were taken to the McLaughlin Youth Center and their charges were given to the Division of Juvenile Justice, police say. 

During the investigation, APD says detectives found Leyland sexually assaulted the juvenile female suspect and faces additional charges of first-degree sexual assault and second-degree sexual abuse of a minor.

Court documents revealed that Brehmer told detectives she was friends with both juvenile suspects and Leyland. According to the complaint, an investigation showed Brehmer and McIntosh made contact with all three before Hoffman's murder.

Denali Brehmer was arraigned Sunday. She is being held on $200,000 bail, $100,000 for each charge of first-degree murder and evidence tampering.
