Fifteenth Judicial Circuit, Palm Beach County Case # 98-12923

Sentencing Judge: The Honorable Marvin Mounts

Attorney, Trial: Gregg Lerman – Private

Attorney, Direct Appeal: Gregg Lerman – Private

Attorney, Collateral Appeals:  Suzanne Keffer – CCRC-S


Date of Offense:           11/26/98

Date of Sentence:         05/10/02



Circumstances of Offense:


In October and November of 1998, Amanda Ingman began trying to locate her drug supplier and “occasional pimp,” Thomas Thibault, to purchase some cocaine.  Thibault contacted Ingman at a house where she was living with her boyfriend, Bryan Harrison, and his roommates, Charlotte Kenyan and Daniel Ketchum.  Harrison became upset when he found out that Thibault called Ingman.


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


After the argument between Thibault and Harrison was resolved, Chamberlain, Thibault, Dascott, Ingman, and Harrison snorted cocaine in Ingman’s bedroom.  The group then went out to get more cocaine, and upon returning to the house, Harrison and Ingman went inside, while Chamberlain, Thibault, and Dascott remained outside and discussed a plan to rob the residents of the house and steal the electronic equipment from the house. 


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


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


Ingman and Thibault awakened Charlotte Kenyan, who had been sleeping in a back bedroom and placed her in the bathroom with Harrison.  Thibault then “emptied the gun” into Harrison and Kenyan while Chamberlain stood by his side.  Harrison was not dead, so Thibault and Chamberlain went 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, Ingman later went to the house of Harrison’s father and told him of the murders.  Police were alerted to Chamberlain’s involvement by Ingman.
