Thanks to Hollywood, most Americans have seen a few frontier firearms.

In the movie “Unforgiven,” Clint Eastwood’s character wielded a 10-gauge double barrel shotgun as he tracked down the town bully, Little Bill.

James Arness, as Sheriff Matt Dillon on “Gunsmoke,” holstered a Colt .45 as he brought bad guys to justice.

John Wayne’s Davey Crockett blasted away with a Kentucky Flintlock as he tried to defend the Alamo.

Now, at the Alamo, an exhibit with more than four dozen weapons tells the story of frontier firearms, how they evolved from single-shot Flintlocks in 1836 at the siege of the Alamo, to modern weapons just 40 years later.

KANSAS CITY, Mo. — Authorities say seven people were shot to death and one was wounded in attacks in a small southeastern Missouri town, and the suspected gunman was found dead from an apparent self-inflicted gunshot wound.

Missouri State Highway Patrol Sgt. Jeff Kinder said Friday morning he could not release any information on the motive or whether the 36-year-old gunman and the victims were connected. Kinder said authorities found the body of an older woman who died of natural causes, but said “we’re not calling her a victim at this time.”
