The family of murdered Border Patrol agent Brian Terry has reportedly filed a $25 million wrongful death suit against the Bureau of Alcohol, Tobacco, Firearms and Explosives -- claiming Terry was killed with AK-47s that were knowingly sold under the Fast and Furious gunrunning probe to a straw purchaser for drug cartels.

Fox reports:

In a 65-page complaint, attorneys for the family claim ATF "wrongdoing" in Fast and Furious.

"ATF's failures were not only negligent but in violation of ATF's own policies and procedures," the complaint claims.

The family has also filed suit against the Lone Wolf Trading Company seeking unspecified damages for selling the weapons to the straw purchaser.

The suit says Lone Wolf knowingly sold "hundreds of weapons" to various straw purchasers and realized "hundreds of thousands of dollars in profits from these sales."

The suit alleges that "but for defendants' negligent and illegal sales ... Brian Terry would not have been murdered in the Arizona desert on December 14, 2010."

The family is seeking a jury trial.
