Wildlife officers captured an alligator Saturday they believe was responsible for fatally attacking a woman while she was out jogging.

The 9-foot, 6-inch alligator was trapped just under the bridge where Yovy Suarez Jimenez, 28, was last seen, Florida Fish and Wildlife Conservation Commission spokeswoman Dani Moschella said.

Two human arms were found inside the alligator's belly, Moschella said.

Authorities still aren't sure how the alligator attacked Jimenez. Witnesses had reported seeing a woman matching Suarez's description dangling her feet over the water's edge on Tuesday, but no one saw an attack.

A medical examiner said the alligator attacked while she was on land and then dragged her body into a canal.

Suarez's death is the 18th confirmed fatal alligator attack in Florida since 1948, Moschella said. Nine other deaths are unconfirmed.
