About 160 memorial posters of fentanyl victims now surround a downtown Tulsa plaza, a grim measure of the epidemic's toll on Oklahoma families.

Families Supporting Families held a vigil Aug. 27, as faces of the dead looked out from the row of posters. Rebekah Brown, whose son Cole died after taking what he believed was a real Percocet laced with fentanyl, leads the group's awareness effort.

"We had maybe five or six posters at the very beginning and now we're surrounding this plaza," Tulsa County District Attorney Steve Kunzweiler said at the event, according to KTUL.

Kunzweiler said the deaths keep coming. He described speaking with someone building a sober living program whose client died at a hotel that same weekend.

The vigil came roughly two weeks after Gov. Kevin Stitt signed two new laws targeting fentanyl. One requires fentanyl education for every Oklahoma student, covering the drug's dangers along with mental health and suicide prevention. The other, known as Leo's Law, adds fentanyl to the drug panel used in Department of Human Services child welfare cases.

Leo's Law, Senate Bill 633, is named after Leo Towe, a 3-year-old Oklahoma child who died from fentanyl poisoning during an overnight visit, according to OKC Fox. The bill passed the Oklahoma Senate 47-0 on May 14 and appropriates $1.22 million through a new Child Welfare Fentanyl Testing Revolving Fund, according to an Oklahoma Senate press release.

The law expands Oklahoma's definition of a "drug-endangered child" to include children exposed to fentanyl or fentanyl analogs. It directs DHS to conduct a safety analysis and seek parental consent for drug screening. If a parent refuses, DHS must notify the local district attorney within 72 hours.

Stitt said the standard drug panel previously tested for only seven substances and did not include fentanyl.

Brown said her son Cole's counterfeit pill contained enough fentanyl to kill three adults. She told KTUL the group hopes it never reaches 200 posters, a number she said matches the daily fentanyl death toll.

Jon Echols, a candidate for Oklahoma attorney general, also attended the vigil. Echols said he would commit additional resources to local prosecutors to investigate and prosecute fentanyl dealers if elected.

Sen. Todd Gollihare, R-Kellyville, and House Speaker Kyle Hilbert, R-Bristow, sponsored Leo's Law. In a May 14 statement, Gollihare said the bill gives child welfare professionals and law enforcement tools to identify fentanyl exposure and protect children.

Families Supporting Families plans to continue adding posters as long as the deaths continue.
