Investigators in Orange Beach are looking into why more than $1 million in narcotics washed up on shore over a two-day stretch last week.

WKRG is reporting that people walking along the shoreline between Lei Lani Condos and Phoenix 10 Condos off Perdido Beach Boulevard spotted the packages.

It is believed the drugs were tossed into the Gulf from a vessel. Barnacles on the watertight packaging indicate they may have been in the water for some time.

According to investigators, the first day turned up 21 pounds of marijuana and a kilo of cocaine. The following day, another 38 kilos of cocaine were discovered.

Orange Beach Police has contacted U.S. Customs and Border Protection, as well as the U.S. Department of Homeland Security and the U.S. Coast Guard Investigative Service in Mobile.
