ST. LOUIS, Mo. (AP) — Federal agents searched for hidden explosives in neighboring St. Louis homes of a man described by friends-turned-informants as an increasingly agitated anti-government extremist who wanted to kill or maim police with booby traps.

Thursday’s search came after David Michael Hagler charged with federal gun counts.

It wasn’t clear what, if any, explosives were found. There were no reports of any search-related explosions.

An FBI agent alleged in the criminal complaint that informants described Hagler as a highly intelligent, anarchist “Rambo” type with a stockpile of firearms and 10,000 rounds of ammunition.

The affidavit says Hagler talked of booby-trapping his home to harm any approaching police.

A message left with his public defender wasn’t returned. Hagler remains jailed without bond.
