Q: At the end of the movie “Zero Dark Thirty,” one of the Navy SEALs removed Osama bin Laden’s AK-47 from a wall in his bedroom. Did the U.S. really take bin Laden’s AK-47? If the U.S. confiscated bin Laden’s AK-47, where is it?

—William McKee Jr., Flowery Branch

A: Bin Laden's AK-47 is on display at a museum at CIA headquarters in Langley, Va., according to NBC News. The rifle was taken from the third floor of the compound in Abbottabad, Pakistan, where a U.S. Navy SEAL team killed the terrorist in a raid in May 2011. "Because of its proximity to (bin Laden) there on the third floor in the compound, our analyst determined it to be his," curator Toni Hiley told NBC News. "It's a Russian AK with counterfeit Chinese markings." Hiley said, however, the AK-47 is not the same one seen with bin Laden in propaganda videos. The museum is not open to the public.

Q: What happened to Dr. Lisa Masterson? She was one of the co-hosts on “The Doctors.” I haven’t seen her on there for a while.

—Jerome Bernhardt, Marietta

A: Masterson, an obstetrician-gynecologist, didn't return for the sixth season of "The Doctors," which began earlier this month. The new recurring co-hosts include urologist Dr. Jennifer Berman, family medicine physician and sexologist Dr. Rachael Ross, and Dr. Ian K. Smith, who wrote "The Shred Revolutionary Diet." Masterson has a practice in California and co-developed Therafit shoes (www.therafitshoe.com), which are described as "fashionable, comfortable sneakers and sandals for all hours of a woman's day," on the company's website.
