Tyler – The ATF says it will add resources to investigate a series of incendiary devices found in east Texas in recent weeks.
Spokesman Tom Crowley tells the Tyler Morning Telegraph his agency believes at least some of the incidents are related.
The latest of at least a dozen incidents was a suspected pipe bomb found Monday in the front yard of a business in Tyler.
Crowley said additional agents will be used to conduct interviews and look at surveillance video. Federal officials also told the newspaper they were investigating the discoveries of similar devices during an investigation into church fires last month.
