Wednesday, June 6th marks the 20th anniversary of the death of 16-year-old Dena Dean.
The Tulsa teen disappeared after work in West Tulsa and her body was found in a field a week later.
Members of the Tulsa County Sheriff's Office Cold Case Task Force have been going through evidence for the last two years. They have interviewed witnesses and served several search warrants, but have not named a suspect.
Dean's family will hold a vigil Wednesday morning at Family Fellowship Church, located at 6105 W. 36th St. in Berryhill. The memorial begins at 11am.
Members of the task force will be there to staff a command post and speak with anyone who wants to offer potential leads on the case.
The task force also set up a special tip line at 918-388-7686.
The tip line will be staffed through Friday, June 8th.
