PLANO - The FBI Joint Terrorism Task Force and the Plano and Garland bomb teams spent Monday night and early Tuesday morning searching a home in the 3200 block of Anchor Drive in Plano.
At one point overnight, they removed an explosive device from the home and detonated it in Kaufman County.
Neighbors said three people left the home late Monday as investigators arrived and issued a search warrant. Police confirmed that the home is that of a man they suspect may have set off an explosive device near a natural gas line Monday over a mile away.
However, police will say the search is linked to that investigation.
The man was critically injured near the gas line explosion on West Parker Boulevard and remains hospitalized in critical condition. Police said they believe he intentionally set off an explosive device near the gas line and injured himself when it exploded.
Authorities said they do not believe the man's story that he was the victim of a hit-and-run crash.
Police said they are still searching for a motive for the explosion. They also want to know what type of an explosive device was used. The only clues the FBI found at the scene were pieces of shrapnel in the wooden fencing near the gas line.
Authorities said they are not commenting on other evidence taken from the home on Anchor Drive overnight. The FBI and police were seen leaving with boxes of items shortly before they left the neighborhood just before 4 a.m. Since then, an older couple returned to the home.
Neighbors said the family has lived there for years and is very nice. Neighbors also said the son who lives there is often out and about and doesn't seem to hold down a job. They said he typically carried a backpack with him.
One neighbor told News 8 the son seemed to change over the last couple of years. He said his neighbor started running at night, saying he "was in training." That same neighbor said the young man lived a minimalistic life, saying he was against modern technology, but would then talk about spending hours on his computer.
The FBI said the next step for the agency is to determine whether police or the FBI will be the lead agency in investigating this case.
