Lewis-Clark Valley Serial Killer

08/02/2025

Detective Jackie Nichols with the Asotin County Sheriff Department in Washington State wrote this proposal to change the DNA law and the how this change could make CODIS and other similar data bases a more powerful tool for law enforcement. The laws that are in place now have not caught up to the advances of forensic science. The steps to compare DNA of a possible suspect to the forensic evidence found on / or near a victim is tedious and works in the perpetrator’s favor and not the victim. The backlog of cold cases is ever growing and until changes in DNA laws happen the backlog will continue to grow, this means the victims do not get the justice they deserve and the families and friends of these victims are left not having answers as to what happened to the ones they loved.
Please contact this page if you have ideas of who should be contacted to help make this change happen.

Justice for Homicide Victims Act Goal: Add a category to the list of maintained/tested data in CODIS. The current list was established by the 1994 DNA Identification Act. This list currently includes convicted offender DNA, crime scene DNA, unidentified remains DNA and familial DNA of missing p...

Diane Marie Schulte went missing from her home on Delaware Ave on 3/25/1977 from Nampa, Idaho. She left her wallet containing money, wedding ring and her car in the driveway at her home. Diane enjoyed reading and she would walk to the library that was approximately a 2 minute walk from her home.
Diane was married to Fred Schulte at the time of her disappearance and they had a good relationship according to those that lived close to the couple. Fred agreed to take a polygraph test about his wife’s, however Fred took his own life on 4/3/1977 before the test could be done. Law enforcement does not consider him a suspect in Diane’s disappearance.
Researching Lance Jeffrey Voss and the areas he lived, the people that he knew in those areas and the cold cases and missing persons in those areas, Diane Marie Schulte’s case was looked at as her being a possible victim. Voss has a history of being an avid reader since he was a young man and frequented libraries and at the time of Diane’s disappearance he was living in Melba, Idaho and his childhood friend had a mechanic shop in Nampa, Idaho not far from the library and Diane’s home on Delaware Ave in Nampa. Voss was also attending college in Boise, Idaho at this time.

On the 42 anniversary of what is referred to as the Lewiston Civic Theater murders my thoughts go to Steven Pearsall and his family. Our family, Kristina & Brandy, their bodies found and the question of where they were was answered. Steven’s family does not have the answer to where Steven is or a place to pay their respects except in their hearts.
On September 12, 1982 Steven was at TJ’s Pantry working until about 3pm, his girlfriend Carol picked him up and took him to the the cafeteria at the Lewis Clark State College where he worked a few hours and then she picked him up and took him to the Lewiston Civic Theater to do his janitorial job at around 7pm. Carol went back to Lewiston Civic Theater around 9pm to pick up Steven to go to a retirement party for TJ’s Pantry employee. After the party Carol to Steven to his apartment to pick up his laundry and dropped him off at the Lewiston Civic Theater around 12:15am. Steven entered the West side door of the Lewiston, he had an army green duffle bag with dirty laundry with him and a brown and tan jacket. He was wearing a velour pull-over, a long sleeved shirt, beige pinstripe shirt and beige corduroy pants. Carol witnessed Steven going into Lewiston Civic Theater, as did two other friends of Steven. A Lewiston Police Officer also witnessed Steven entering the theater.
Steven did not have transportation and he left his clarinet at the theater which was unusual because the instrument was dear to him.
There was another person, Lance Voss, that was at the theater. He admits to being at the Lewiston Civic Theater with Steven working on sets from around 7pm until around 9pm. He left the theater around 10pm and went to the Red Baron Pizza and had two beers. He returned to the Lewiston Civic Theater around 11pm. He hurt his back and decided to lay down in the green room around 11:30pm and fell asleep. He claims not to have slept very well and at 6am he woke up and drove home. Lance told law enforcement no one else was at the theater.
Although so many years have gone by our families still have hope that there will be a tip to come in that will help find the location of Steven Pearsall. If you have information please private message this page. All information is confidential and is given to law enforcement.

Today, 61 years ago, the body of Diane Taylor was found behind 1055 N. Lockwood in the Austin neighborhood in Chicago, Illinois, she had been stabbed and slashed, with a stab to her heart being the cause of death. Her navy blue shorts, white socks, white tennis, blue framed glasses, 3 keys, blue billfold with her YMCA ID and 2 rings were missing. Law enforcement believe that Diane was murdered elsewhere and her body dumped in the alley, her autopsy findings lead law enforcement to believe that she had been murdered approximately 36 hours prior to her body being found.. Diane Taylor was seen walking around 2:10pm down an alley behind the Austin YMCA located at 501 N. Central Ave, Chicago, Illinois. She attended the day camp at the YMCA. Diane had asked a counselor at the YMCA to help her unwrap a lollipop and a friend stated that then Diane left walking down the alley behind the YMCA around 2pm. Diane’s mother Rita returned home from work around 6:30pm and Diane had not returned home. Rita reported Diane missing to the Chicago PD approximately 9:30pm on August 1, 1963. That Saturday a report of a a teenager possibly 18-19 years old driving 1949 two door black Ford with damage to the left front fender above the tire had been seen coming out the Lockwood alley at approximately 6:45am and another report of hearing a car stop and a car door slam around 6:30am - 6:45am.
The suspect in the Lewis-Clark Valley murders and missing persons, Lance Jeffrey Voss, is also a suspect in Diane Taylor's 1963 murder. Her murder is believed to be Lance Voss's first victim.
Cases older than Diane's case have been solved in recent years some by forensics and others by tips that are the missing piece of the puzzle.

Donna Lass went missing from the Sahara Hotel Casino in South Lake Tahoe, California on September 6, 1970, her skull was found in 1986 near Hwy 20 and I80 in Placer County and recently identified as Donna Lass through DNA. She was a nurse for the hotel and her case along with Judith Hakari have been referred to in some news articles as the "Nightingale Murders" and some theorists believe that she is a "Zodiac" victim. Putting that notoriety aside and looking at facts about Donna Lass's cold case, she had purchased a new car before her disappearance, the "key" which was a postcard giving directions to find her body is bares similarities to directions used by those who ran "Gimmick Car Ralleyes" also known as "Poker Runs". There was also real estate investments booming that area and some of these facts we applied to Voss, who worked as a salesman at Auto City in Santa Clara, California, held a job at Realcom Real Estate and he was very active in Gimmick Car Rally racing belonging to a team called Bay Area Rally Force (BARF). A member, Madelyn Taylor, of B.A.R.F. said that their team raced the length of Nevada and went through the Lake Tahoe area. Voss drove a 1968 blue Saab at that time (photo included in this post is an example of what the car looked like.) If you have any memories or information message this page.
