Authorities have charged two men and a woman in connection with last Friday’s death of another young woman.

The 20-year-old victim, who was not identified, was found unresponsive shortly after 6 a.m. Friday at a home on Apple Court, off Rolling Hills Drive, in the Krakow area. It is believed she died after ingesting heroin.

She was transported by Washington Ambulance to Mercy Hospital Washington where she was pronounced dead about 7:15 a.m., according to Capt. Chuck Subke of the sheriff’s office.

Authorities said the victim was with the other three at the home on Apple Court and all four allegedly used heroin purchased Thursday, Aug. 20.

The case was investigated by the Multi-County Narcotics and Violent Crimes Enforcement Unit based in Franklin County and the sheriff’s office.

That investigation resulted in the arrests of the three suspects who are each charged with felony distribution of a controlled substance.

The suspects charged are: Kyle L. Kleinheider, 20, Washington; Nathan T. Burton, 20, Union; and Alexis N. Dames-Hudson, 19, Union. They were being held in lieu of $50,000 cash-only bonds.

Sheriff Gary Toelke said all three were still in custody in the county jail Tuesday.

Prosecuting Attorney Bob Parks said he is still waiting to receive reports from investigators.

But based on those reports and evidence from the St. Louis County Medical Examiners Office, Parks said he may file additional murder charges in the case.

That’s based on the recent heroin initiative adopted by several county law enforcement agencies in the St. Louis region, Parks explained.

Friday’s apparent heroin related death followed the arrest Thursday of four people suspected of trafficking and using heroin. They were taken into custody for questioning after investigators foiled a drug sale near the Washington city pool.

Detective Sgt. Scott Reed, narcotics unit commander, said officers followed up on an anonymous tip and set up surveillance in a parking lot near the pool.

Investigators questioned two people, a 20-year-old man and a 35-year-old woman, who said they were waiting there to purchase heroin.

While officers were on the scene, an 18-year-old man arrived in a car and was taken into custody, Reed said.

He gave officers permission to search, according to Reed, and they seized approximately 3 grams of suspected heroin, which amounted to about 32 individual doses.

That investigation led officers to a home in the 200 block of Fair Street, south of the city pool, where they questioned a 19-year-old man and seized more drugs.
