HAYS COUNTY, Texas -- A blast in the night shattered the quiet of a country neighborhood in Hays County. Now, a criminal investigation is underway.
Deer Lake Estates sits between Kyle and Wimberley in Hays County.
Neighbors describe it as a peaceful place where people come to retire or escape to their ranch from busy city life.
"It was quiet for a long time until last night," said neighbor Kathy Vermillion.
That's when the Austin Police Bomb Squad detonated four to six pounds of C-4, a military grade explosive not available to the public.
"Just all of a sudden, [there was] this incredible big boom and we knew they had found a bomb. The windows shook. [My] grandson [was] running with a pillow over his head," said Vermillion.
"It was huge. Shockingly huge. Pictures fell off the wall," said a woman, who did not want to be identified.
It all started Tuesday when Hays County constables served papers at a home on Deer Lake Estates Road. They received a tip there could be explosives on the property next door. On Wednesday, investigators found a bomb inside a cave.
"I hike up there. These folks who own the property are our neighbors and friends," added the woman.
She said several law enforcement agencies spent the entire day in their neighborhood, searching all the caves and surrounding land on the property.
"In the beginning, it was a couple of police. Then it was the bomb squad checking it out," she said. "Then, it was X-ray equipment to look at what they found in the cave. Then it was ambulances and fire trucks."
Neighbors said they're ready to get things back to normal and the peace and quiet they enjoy.
No one was hurt in the incident, but the fire marshal said the explosion did break one neighbor's windows.
