A man from Dillingham was arrested at the Anchorage airport last week, after a number of factors tipped him off to police, including an informant, eye-witnesses testimony, and a drug-sniffing police dog.

The event started on the afternoon of Nov. 19. According to charging documents, Andrew Straley, 50, of Dillingham, arrived at the Ted Stevens Anchorage International Airport, empty-handed.

He had a layover before boarding another flight to Dillingham two hours later, and authorities say he was overheard saying he "needed to go pick something up" before catching that flight.

Airport security footage showed Straley leaving the terminal and getting into the passenger seat of a red sedan, which DMV records showed belonging to Straley.

An hour later, authorities state in their report that Straley returned to the airport in the same car. A police car labeled "K9 Unit" was parked nearby, and police say the red sedan drove away "as if to avoid contact with the police" and parked near a different gate.

Straley entered the terminal again, this time carrying with him a blue colored roller bag, and authorities were waiting to make contact with him. The bag, investigators say, contained over 100 grams of methamphetamine, individual baggies typically used for portioning meth, and several glass pipes often used to smoke meth.

Police say this amounts to a drug selling operation, rather than a personal supply. "This amount of methamphetamine is indicative of a distribution quantity based off of a single dosage unit typically ranging from 50 mg or more," investigators wrote.

In addition to the behavior they'd observed, investigators were already watching Straley due to a tip from an undisclosed informant, who previously tipped off authorities that Straley tried to sell him meth.

Straley was arrested, according to federal charging documents, for possession with intent to distribute a controlled substance.
