"One other policeman has pleaded not guilty so he is waiting for a day to appear in front of the Tribunal."
"They have been dismissed [from work]."
Another officer is awaiting a decision from the tribunal.
The officers have not been named.
Crichton is serving a life sentence for killing a taxi driver at gunpoint last year.
He is yet to enter a plea over Dalton's death and will appear in court again next week.
Dalton was in Samoa visiting relatives when a mental health episode led family members to seek support from the authorities.
He was in jail at the time of his death because he had become violent and police needed to restrain him.
