MILTON, Wis. -- The Milton School District is looking to take action after three middle school students overdosed on heroin.

Police are also recommending charges in the case, which stems from an incident on May 16. Police said three eighth-graders from Milton Middle School overdosed in a park. All three have since recovered.

As police investigate, the school is looking to reach out to students.

Police said a first encounter with heroin almost ended a life before reaching high school.

"One of the juveniles had actually stolen (heroin) from one of his friends' parents, and they subsequently snorted it at a residence in Milton and went to an area park, where all three boys started suffering from the side effects of heroin use," said Milton Police Chief Jerry Schuetz.

A passer-by in South Goodrich Park found the three teens, one unconscious, and got help.

Investigators said the eighth-graders didn't even know what they put in their system.

"One of the juveniles testified that they thought it might have been cocaine, which is why I think that they snorted it. The other juveniles were not exactly at all sure what they were using," said Schuetz.

The middle school was planning an anti-drug presentation in the fall, but said it will now accelerate efforts to reach students.

"We need something now. The summer's coming; we just need to catch them now," said Milton Middle School Principal Tim Schigur.

Police will speak to the school Friday, before students break for summer vacation.

"(We want to encourage students to) make better choices, (to) make something like this less of a viable option. We can't control life outside of the school building, but can we at least give them the knowledge of this is what could potentially happen if you choose these kinds of things," said Schigur.

Police and school officials said the students made a bad choice that nearly had an even worse consequence.

"To be quite frank, I think that we're very fortunate that this wasn't a more negative outcome," said Schuetz.

Milton police are recommending that the 15-year-old suspected of stealing the drugs be charged with felony distribution to minors.

Police said they also want charges of failure to render aid and contributing to the delinquency of a minor filed against Lori Bone, 32.

Police said they believe the heroin was Bone's. Police said they want her side of the story, but said she moved to Michigan and is not cooperating in their investigation.
