Experts tracking a great white shark through the Gulf of Mexico have received electronic signals indicating the shark's route could lead to Texas.
Data from the group Ocearch shows another "ping" was recorded Tuesday morning from the shark dubbed Katharine.
The 14-foot shark was tagged last August off Cape Cod, Massachusetts. The tag sends a signal when the 2,300-pound shark comes to the surface. Officials did not immediately provide an estimated location Tuesday for Katharine.
The Houston Chronicle reports a satellite on Sunday put Katharine about 140 miles west of Sarasota, Florida. Researchers say in another week the westbound animal could be past the Mississippi River and eventually reach Texas.
Robert Hueter with the Mote Marine Laboratory in Sarasota says tags can last up to five years.
