On November 12, Randall Saito escaped from the Hawaii State Hospital.

How he did it is still a mystery.

"How did this happen, I think we all want to know how did this happen," Dr. Virginia Pressler , director of the State Department of Health said. 

U.S. Marshals brought Saito back from California to Hawaii this week.

With charges pending, legal rules prohibit the State Attorney General from releasing certain information about Saito's case.

Attorney General Doug Chin spoke generally about what would typically happen to find out how a certain suspect escaped and if that suspect had help.

"Typically what would occur is investigators would be doing the following. They'd be interviewing witnesses, different people involved but after that, there would be another phase that takes several weeks, basically gathering electronic evidence," Chin said. 

That includes using search warrants to seize any computers or cell phones that may have been used.

"My understanding of the status of those investigations is yes I can report that they're underway, I cannot tell you the persons of interest or suspects but can say we expect to have that investigation wrapped up within the next several weeks," Chin said. 

The State Department of Health say they're already taking action.

A new interior fence is said to be 30 days away from being completed, implementing GPS trackers on the hospital's radar.

Headcounts and unannounced searches will also happen more frequently.

"Certainly there are some items that need to be addressed at the hospital from procedures to security, but we know at least what needs to be done," Sen. Rosalyn Baker said.

While the investigations continue, lawmakers may be taking initiative on their own in the upcoming legislative session in regards to policy to keep patients in their place.

"Can all of the patients there regardless of their level of freedom, I want to mail them something, who here checks their mail?" Sen. Jill Tokuda said. 

"The way the mail policy reads is if we have a reason to suspect something may not be appropriate, we will open the mail in front of the patient. In absence of that we do not do it, it's a right as the AG said, that policy is under review and it may be changed," William May, Hawaii State Hospital administrator said.
