HARRISBURG, Pa. (ErieNewsNow) - Hundreds of local, state and federal law enforcement officials have been working to track down Michael Burham since his escape from the Warren County Jail on July 6. 

Burham remains at-large, but navigating Pennsylvania's wilderness, finding food and clean water- all while remaining unseen- is especially challenging this time of year. 

“He's been physically active, he's feeling his batteries drain,” said Erik Kulick, the Founder and Chief Instructor at True North Wilderness Survival School in Pittsburgh. 

Kulick pairs his law enforcement and emergency medicine background with an extensive knowledge of the outdoors to train others. He says adaptability and resiliency may be working in Burham's favor for the time being, but it’s unlikely to last. 

“We’re in one of the hottest periods on record in decades. Rain, insects, and other harsh conditions- he's got to deal with his medical issues like dehydration, he's got to keep his spirit up, he’s got to find water. I don't see how he can meet his survival priorities and evade,” said Kulick. “He's going to overheat. He is going to be dehydrated. Being caught in a rain shower and dealing with bugs all day, trust me, that is going to take its toll,” he added. 

Burham, who state police describe as “a self taught survivalist with military training," has been on the run for over a week. But even with any stockpiles or supplies, and regardless of Burham's level of training, Kulick says he’s still vulnerable to the elements. 

“I just don't think he could survive that long in these conditions, absent not having support from some kind of third party,” said Kulick. “It's hard. It's hard work to survive.”  

Unlike law enforcement, who have the manpower and resources necessary to continue the search, Kulick believes time is not on Burham's side. 

“I think between hunger, dehydration, heat and general discomfort- despite his desire to want to stay away from law enforcement- that is going to draw him in toward a public setting where he's going to be seen or where he is going to be caught,” said Kulick. “I just can't imagine this not breaking him down. He's going to make a mistake and that's going to benefit law enforcement,” he added. 

As of yesterday, there is a $22,000 reward for any information that helps lead to Burham's capture. Anyone who sees Burham is asked to call 911 immediately and advised not to approach him. Any tips or information should be reported by calling the command post at 717-265-9650.
