Update for Dec. 20
The King County Sheriff's Office has provided an update on a Dec. 18 drug ring busts in White Center and Burien, the culmination of an 8-month long investigation:

An 8 month investigation conducted by the King County Sheriff’s Office resulted in the seizure of narcotics, guns, money and the arrest of 8 people for trafficking narcotics.

The investigation started in April when detectives learned that about a narcotics dealer that had the reputation of selling high quality cocaine and heroin in the Burien area. Detectives learned that the suspect had been sought by investigators before for dealing narcotics but would shut down his operation when he suspected police were closing in.

Detectives spent months conducting surveillance on the suspect’s residence and other locations they learned were connected to the operation. On Wednesday the King County Sheriff’s Office served search warrants on six locations including a residence in the 1600 blk of SW116 St. in Burien and a residence in the 1200 blk of SW107th St. The other locations included a residence and storage unit in Renton, and a house in Federal Way.

8 adults, 7 of them family members were arrested in the raids and 6 children were placed in CPS custody.

In total items seized were:

1.25 pound of cocaine with a street value of $22,000
6 ounces of heroin with a street value of $2,000
$65,371 in US Currency
5 firearms all of which appeared to be packaged for transport into Mexico (“We believe the ammo that we found was packaged to ship to Mexico. It had been wrapped in multiple layers of tin foil and dryer sheets (like bounce) and multiple layers of cellophane. They do this cause they think the dryer sheets will throw off the dogs and the tin foil will beat an X-ray machine.” - lead detective on the case)
5 vehicles valued at $60,000
