Circumstances of Offense:


In October and November of 1998, Amanda Ingman began tryingto locate her drug supplier and “occasional pimp,” Thomas Thibault, to purchasesome cocaine.  Thibault contacted Ingman at a house where she was livingwith her boyfriend, Bryan Harrison, and his roommates, Charlotte Kenyan andDaniel Ketchum.  Harrison became upset when he found out that Thibaultcalled Ingman.


In the early morning hours of 11/26/98, Thibault enlistedthe help of John Chamberlain and Jason Dascott to deliver some cocaine toIngman and resolve the argument with Harrison.  Thibault told Chamberlainthat there might be a confrontation.  Chamberlain drove his father’s carand picked up Thibault and Dascott.  While stopped at a gas station, Chamberlainshowed Thibault a .45 caliber handgun and ammunition that were stored in thetrunk of the car. 


After the argument between Thibault and Harrison wasresolved, Chamberlain, Thibault, Dascott, Ingman, and Harrison snorted cocainein Ingman’s bedroom.  The group then went out to get more cocaine, andupon returning to the house, Harrison and Ingman went inside, whileChamberlain, Thibault, and Dascott remained outside and discussed a plan to robthe residents of the house and steal the electronic equipment from thehouse. 


Either Ingman or Dascott persuaded Ketchum to open a safe inthe living room.  Thibault then pulled out the .45 caliber handgun andordered Ketchum and Harrison into the bathroom.  Chamberlain helped bystriking Ketchum in the leg with an asp, an extendable police baton. Thibault held Ketchum and Harrison in the bathroom, while Ingman, Dascott, andChamberlain removed the electronic equipment from the house and put them inChamberlain’s car. 


While in the bathroom, Ketchum attempted to overpowerThibault, but he shot and killed Ketchum in the struggle.  Thibault leftthe bathroom and told the others that he had killed Ketchum.  According toThibault and Ingman, Chamberlain then said “no more witnesses” and encouragedThibault to kill Harrison or else they were “all going to die” and were “allgoing to the electric chair.” 


Ingman and Thibault awakened Charlotte Kenyan, who had beensleeping in a back bedroom and placed her in the bathroom with Harrison. Thibault then “emptied the gun” into Harrison and Kenyan while Chamberlainstood by his side.  Harrison was not dead, so Thibault and Chamberlainwent to the car, retrieved more bullets, reloaded the gun and Thibault again“emptied the gun” into Harrison and Kenyan. 


After going back to Chamberlain’s parent’s house, Ingmanlater went to the house of Harrison’s father and told him of the murders. Police were alerted to Chamberlain’s involvement by Ingman.
