The assistant warden at the Agassiz prison where an inmate was murdered by his cell-mate two years ago says changes have been made to better protect prisoners. 

Brenda Lamm is testifying at the inquest of Jeremy Phillips --a 33 year old man strangled by serial killer Michael McGray at the medium security Mountain Institution in November of 2010.

She says McGray had a good behaviour record before he was transferred from a maximum security prison --where he had his own cell-- to her facility where he shared accommodation with his last victim.

She says she never felt manipulated by McGray who has since claimed he is a sociopath who should not have been transferred out of the Kent prison.

Lamm says improvements made since Phillips was murdered include better bed checks by corrections staff to ensure inmates are alive...And not just sleeping.

The victim's mother Lela Phillips is slated to be the last witness before jury deliberations begin.
