Gunman Robs Post Office POSTED: 10:13 am EDT June 6, 2007 RALPH, Ala. -- A gunman robbed a small post office in rural Tuscaloosa County early yesterday and made off with cash. Now, the U.S. Postal Service is offering a $50,000 reward for information leading to his capture. The holdup happened around 8:15 a.m. at the Ralph post office. The tiny community is located in southwest Tuscaloosa County, not far from the Greene County line. A postal inspector said the suspect jumped over a counter and snatched money from a cash register, then fled in a dark-colored Chevrolet, possibly an Impala or Lumina. Authorities said there were no customers inside the facility and no one was injured.
