They lived next door to each other, but neighbors say Dennis and Glen Caldwell didn't exactly get along.
"They are just at each other all the time," said Johnny Ruff, a man who has lived next to the Caldwells on Haven Heights Drive for years.
"I told them they need to get along, being brothers and stuff, but that doesn't do any good," said Ruff.
The fighting wasn't a secret to law enforcement.
Since 2009, The Bedford County Sheriff's Office has answered 59 calls at Dennis Caldwell's property.
"They were calls for loud music, noise complaints," said Bedford County Sheriff Mike Brown, adding that the calls contained no "red flags."
"There as certainly nothing that would have given us any indication of what was going to happen Monday," said Brown.
Deuties say Dennis shot Glen and his son, Michael Caldwell, before engaging deputies in an hours-long standoff that ended when Dennis reportedly tried to burn down his own house while still inside.
Why the fighting escalated to violence is still unclear, but neighbors believe an unfinished garage may have something to do with it. The building was going up between the Caldwell houses.
Friends say the brothers have been fighting over property for years, even though both own their respective properties outright. Investigators plan to get the full story out of Dennis, when he's able to talk.
"(Dennis) will be interviewed, just as soon as he's physically able to speak with our investigators," said Brown.
Dennis Caldwell is being treated for smoke inhalation at the University of Virginia Medical Center. He's currently charged with malicious wounding and weapons violations, but deputies say he could face more severe charges in the near future.
