Authorities say a drug dealer sold fentanyl-laced cocaine that killed three people in an Orange County home.

He’s accused of selling fentanyl-laced cocaine to two couples in October at a house on Balboa Island in Newport Beach, the U.S. Attorney’s Office said Friday.

The victims were identified by the Orange County Sheriff’s Department as Samantha Haiman, 45, of Riverside, and Andrew Adams and Desiree Temple, both 43, of Yorba Linda, according to KTLA.

According to the U.S. Attorney’s Office, the couples had enjoyed a dinner together, and one of them decided to purchase cocaine for the group.

“They eventually contacted Dick, who agreed to sell them $200 worth of cocaine, which he delivered to the house where the couples were staying,” the U.S. Attorney’s Office said in a statement.

“After snorting the purported cocaine, all four suffered overdoses, and three of the individuals were pronounced dead at the house the next morning.”

“In most of the cases, the victims did not know they were ingesting fentanyl, which can be deadly in tiny amounts,” the U.S. Attorney’s Office said.
