The house, shielded from public view, is where investigators suspect the boat bomb was built Historically, ships get in and out of Yemen easily, and there is a long tradition of smuggling. U.S. Navy divers are still working the waters of the area trying to recover clues. Sources say they are looking for body parts of those who brought a small skip along the port side of the Cole and triggered the explosion. Investigators have set up crime labs in tents at the boat ramp believed to have been used to launch the suicide attack, about six miles from the Cole's location in the harbor. At the house where the explosive device was believed to have been put aboard the boat, FBI agents are said to have removed a great deal of evidence.
Yemeni police believe they have also found three other locations used by the bombers.
So far, the investigation is still limited to the city of Aden. One U.S. official said that more than 100 people had now been detained or questioned in connection with the attack. The remains of the last four sailors who were among the 17 killed in the attack arrived at Dover Air Force Base in Delaware late Sunday morning. The families of two of the victims, Kenneth Clodfelter and Patrick Roy, attended a ceremony on the tarmac as the caskets were removed from the aircraft. The families of the other two sailors were not in attendance.
