There's a drug epidemic sweeping the country and it knows no political boundaries. Investigators say the daughter of a Wisconsin legislator who's worked to stem the opioid epidemic provided the drugs that caused the death of a pregnant woman.

It's a very tragic turn in what's been a very public drug battle for 28-year-old Cassandra Nygren.

The investigation stems from June 2nd, 2017 -- when Brown County sheriff's officials found a woman without a pulse, believed to be pregnant.

31-year-old Jennifer Skeen was 30 to 32 weeks pregnant, officials said. She died as a result of a drug overdose, and officials said fentanyl was found in her system.

An investigation revealed Cassandra Nygren and Shawn Gray as persons of interest.

Officials said on October 10th, attempts were made to arrest Nygren and Gray in a vehicle.

Probable cause was developed during an investigation and interviews, officials said.

"Mr. Gray and Ms. Nygren engaged in a pattern of extremely reckless and destructive behavior," Todd Delain, chief deputy with the Brown County Sheriff's Office said Thursday.

Nygren made her first court appearance Thursday -- a probable cause hearing.

The assistant district attorney said a cellphone shows a conversation between Skeen and Nygren that indicates they planned to meet for a drug transaction, and that Nygren admitted to deputies that she provided Skeen heroin mixed with fentanyl.

Cash bond was set at $50,000 for Nygren, according to WLUK.

She's due back in court next Thursday, October 19th.

Gray was also in court for a probable cause hearing. The assistant DA said he delivered the heroin mixed with fentanyl, but never admitted to this. The information came from Nygren, the assistant DA said.

The assistant DA also brought up the fact that Gray has failed to register as a sex offender.

He'll be back in court next Friday. Cash bond was set at $50,000, according to WLUK.

Investigators have recommended the below charges, though formal charges haven't yet been filed, according to online court records.

Nygren:

First degree reckless homicide (two counts)
Delivery of a controlled substance/heroin
Neglecting a child
Keeper of a drug house
Possession of a Schedule II controlled substance with intent to distribute

"The illegal use and distribution of opioids clearly destroys individuals' families and the fabric of our community. The family of the victim has been notified of the arrest, and they ask for privacy at this time. We are asking that if anyone is involved in the illegal use of drugs, call the Brown County Tip Line or Green Bay Crime Stoppers," Delain said.

Nygren's family has been open about Nygren's drug use. She was convicted of possession of narcotic drugs in 2015 and 2010, according to WLUK. Nygren's struggles with drugs have prompted her father, Republican state Rep. John Nygren, to sponsor numerous bills aimed at curbing opioid addiction over the years. He issued the below statement Wednesday:

"First and most importantly, I offer my sincere and heartfelt condolences for the loss of life. There are no words that we as a family can offer to give any real comfort for the tragic loss. To the family and friends of the victims of this tragedy, please know that you are in our prayers and that our hearts are heavy. Cassie has publicly struggled with addiction and recovery for several years. This is a strong reminder of how fragile the road to recovery is. We will continue to support and pray for her recovery. This is just another example, in a seemingly endless line, of the disastrous and destructive consequences addiction continues to have on families and communities nationwide. These stories are the motivating factor behind all our work in the legislature to fight this epidemic. In this time of extreme sadness and sorrow, I request that privacy and respect be extended to those grieving from their loss."
