"I'm actually just glad I didn't wake up," homeowner Keith Monley said.
Monley says he's reassessing home security after someone broke in overnight.
"I'm thinking that we're vulnerable," Monley said.
He, his wife and son were sleeping upstairs while someone got through the locked front door, grabbed several bags from the front hall, and then hit the garage, rifling through the car, stealing more stuff.
"Now it's getting to a point where it's scary," Vt. State Trooper John Bruzzi said.
State Police say the home invasion at the Monleys' is the most brazen the thieves have been.
"Because who knows what's going to happen if a confrontation occurs? Homeowners are going to act different depending on who they are. You wake up at three in the morning and someone is standing in your living room. A lot of bad things can happen," Bruzzi said.
The crime spree started in Fairfax three weeks ago-- thieves going into unlocked cars swiping anything they can quickly cash in to buy drugs.
"They were coming in 15 at a time," Bruzzi said.
And investigators say it's escalating. They believe the same people may be involved in the latest thefts in South Hero.
"It's the same M.O.; the same time, the same exact things they're doing and the same exact stuff they're taking," Bruzzi said.
Keith Monley hopes they catch the thieves, but right now is focused on getting better locks and even a security system so it doesn't happen again.
"I'm more frustrated than I am angry," he said.
State Police believe the thieves are driving to neighborhoods and they want to hear from anyone who saw anything suspicious in the Sunset View Road area of South Hero early Tuesday morning. They say you can protect yourself by keeping cars locked, even in your garage. Don't leave valuables in your car. And lock your home, add a deadbolt to doors and motion-activated lights outside.
