Samuel Walker, 29, of Shaon, Miss., got 15 years in prison Friday. The former Army sergeant was convicted of murder-for-hire conspiracy and a weapons charge, according to The Associated Press.
Prosecutors say a co-defendant in 2011 negotiated with people he thought were members of the Zetas drug cartel but were undercover agents, the AP reported. Here's a background story from CBS News.
And speaking of the Zetas, the AP also reported that authorities say they caught an escaped convict in South Texas who was part of a massive prison break last year in Mexico.
