(KPRC) - Two small explosions could be heard as law enforcement officials continued to execute a search warrant at a Memorial-area home Saturday afternoon.
FBI spokesperson Shauna Dunlap said law enforcement officers discovered "potential volatile substances" at the home in the 400 block of Fall River Drive, leading to two controlled detonations.
The first detonation happened shortly before 2 p.m. and the second a couple of hours later.
"For the safety of the nearby public, the safety of the nearby personnel, we needed to dispose of that substance in the backyard of the residence," said Dunlap.
On Friday, the FBI and other law enforcement agencies served a search warrant at two residences in expensive Houston neighborhoods, as well as one near College Station. While the two other homes were cleared Friday afternoon, officials remained at the Fall River home all day Saturday.
FBI agents conducted a search of a home in the 2000 block of Albans near Rice Village and the second home on Fall River Drive. A resident shot video at around 9 a.m. Friday as dozens of law enforcement rolled down his street to his neighbor's home.
"We didn't know what was happening. I talked to a police officer and he said one of your neighbors has been ordering bomb parts," said Justin Campbell.
Public records show the homes are owned by Cecily Horton and Andrew Schneck. They also own the condo in Bryan.
"No arrests have been made and no arrests have been anticipated at this time," said FBI Spokesperson Shauna Dunlap.
As neighbors stood by and watched, agents removed several items from the homes. Dunlap says the safety of the public remained a priority.
"I can't comment except to say that we have obtained a lawful search warrant in this case and because those documents are under seal, I can't comment any further about nature of search warrant or nature of the investigation," she said.
Residents meanwhile said they noticed what appeared to be law enforcement officers sitting in unmarked cars watching the home over several weeks before Friday's raid. Many are concerned about what and whom they may be living close to.
"The world we live in, I guess," said neighbor Travis Broesche. "I don't know the people who purchased about a year ago, within the last year. I've never met them."
Local 2 did some checking on the couple and they're well know in the Houston arts scene, and have ties to some local art museums.
