Jesse William McGraw pleaded guilty for felony offences that caused damages to the hospital's computer system, in Dallas. McGraw had access to around 14 computers located in the North Central Medical Plaza, including a nurses's station computer and a heating and ventilation and air conditioning. The nurses station used to track a patient's progress through the Carrell Memorial Clinic.

McGrow used a transmitted program that allowed him or anyone with his account name and password, to access the computers. 

He also weakened the integrity of some of the computer system by removing security supports like: uninstalling anti-virus programs that made the computer network more vulnerable to attack. In addition, he installed malicious code that was associated with theft of data from the compromised computer, using the compromised computer in denial of service attack, and using the computer in order to send spam. 

 he also took advantage of these information and action for his Electronic Tribulation Army and others who interested in computer crimes.   

McGraw had unauthorized physical access to security locked room containing HVAC computer for downloading a password recovery tool from a website also inserted a removable storage device and executed a program which allowed him to emulate a CD/DVD device. 

Although he denied  but by doing that and control on HVAC he was able to interfere with treatment regimes, including the efficiency of all temperature-sensitive drugs and supplies.
