(CBS News) A woman has vanished at a lake in South Florida, and the chief suspect in her disappearance is a large alligator. The alleged gator ambush happened just before 10 a.m. Friday. A witness told police 47-year-old Shizuka Matsuki was walking her dogs near this lake in Davie, Florida.

It took authorities more than five hours to trap the 12-foot-alligator. Officials reportedly found an arm inside the reptile. Divers are still searching for the missing woman.

“Her husband just called me a half-hour ago, ‘Hey something happened with my wife and by your house in the park, and a couple find the dog, but they don’t find her,” a friend of the victim said.
