Charter boat Capt. Dan Lindley told Channel 4 he was out Sunday afternoon on a dive charter when they spotted the aircraft wreckage 12 to 15 miles offshore. He said he hauled a pices of the fuselage and other parts of the plane onto his boat.
"You could tell it was fresh wreckage; no grass or barnacles," Lindley said.
Lindley said police came Tuesday night and picked up the debris. Police said investigators are trying to determine if the parts match an aircraft that took off from Herlong Airport early Sunday morning.

Milowicki's small plane was missing from its hanger. Airport records show Milowicki entered the airport at 2:04 a.m. Sunday.
