A man suspected of supplying fentanyl to a 25-year-old Moreno Valley woman who died after ingesting the synthetic opioid was arrested Friday.

John P. Biagianti, 30, of Upland was taken into custody following a joint Riverside County Sheriff’s Department and U.S. Drug Enforcement Administration investigation that began last year.

Biagianti was booked by federal agents into a regional detention center, but the specific allegations and bail information were not immediately available.

Sheriff’s Sgt. Ryan Marcuse alleged that the suspect furnished Kyrsten Dauss with fentanyl last August. Deputies were called to her residence in the 10000 block of Sparrow Court, near Pigeon Pass Road, on Aug. 9 after loved ones were unable to contact her.

The woman was discovered dead in the home, and it was later determined that she had been the victim of “fentanyl poisoning,” Marcuse said.

DEA agents and sheriff’s detectives pursued leads that ultimately pointed to Biagianti as the alleged supplier, according to the sergeant.

No other details were available, including background information on the suspect.

Fentanyl is manufactured in foreign labs, and according to the DEA, it’s smuggled across the U.S.-Mexico border. It’s known to be 80-100 times more potent than morphine and is a popular additive, mixed into any number of narcotics and pharmaceuticals.

Sheriff Chad Bianco said there were about 500 fentanyl-induced deaths countywide last year, which represents a 250-fold increase from 2016, when only two such fatalities were documented.
