Marina Deetz, 20, a teacher's assistant from Florida, has been charged with possession of drugs and drug paraphernalia after a teenager's overdose death

An elementary school teacher’s aide from Florida has been arrested on drug charges after police say she sold fentanyl to two teenage boys, one of whom later died of an overdose.

Marina Deetz, 20, was arrested on Wednesday at her apartment in New Port Richey on charges of possession of a controlled substance, possession of heroin, possession of drug paraphernalia and two counts of possession/delivery of a controlled substance.

Police launched an investigation into Deetz after an 18-year-old boy overdosed on drugs this week.

Fentanyl is a synthetic opioid that can be up to 50 times stronger than heroine and 100 times stronger than morphine.

America's opioid addiction crisis has been fueled by deadly manufactured drugs like fentanyl.

According to an arrest affidavit cited by the station WTSP, a 17-year-old boy told police he and his 18-year-old friend had gone to Deetz's apartment and procured fentanyl from the Moon Lake Elementary School employee.

In exchange, the teens gave Deetz cocaine and $50, the witness alleged.

The two young men stayed at the teaching assistant’s apartment, where Deetz allegedly cut the cocaine and fentanyl on black dishes, and all three of them snorted the powder through a blue straw.

Deetz is suspected of selling two boys, ages 17 and 18, fentanyl in exchange for cocaine and $50. The woman admitted to snorting cocaine with the teens but denied giving them fentanyl

When police later searched the woman's home, they reportedly found the dishes, the straw and baggies that tested positive for fentanyl, as well as a rubber container with a substance that tested positive for heroin.

Under questioning, Deetz admitted to using cocaine with the teenagers but denied giving them fentanyl.

The Pasco County Sheriff’s Office has not released any information about the 18-year-old who died, citing an ongoing investigation.

Court records indicate that Deetz was charged with burglary with aggravated battery/assault in October 2019, but prosecutors dismissed the case two months later.
