Police have dropped all charges against the 25 soldiers from Fort Riley, Kansas, who were arrested earlier this month at a house party.

The soldiers, who had faced drug- and alcohol-related charges, still could be disciplined by their commanders.

"From our understanding, all charges have been dropped by police," said Master Sgt. Mike Lavigne, a spokesman for the 1st Infantry Division at Fort Riley. "There are still continuing investigations at the unit level, and those are handled individually on a case-by-case basis by commanders."

The incident happened Jan. 8.

Shortly before midnight, officers from the Grandview Plaza Police Department responded to a complaint about a loud party. A total of 27 people were arrested. Charges against them included misdemeanor possession of marijuana, criminal use of a weapon, hosting minors consuming alcohol, and unlawful noise, according to the police report.

The soldiers who were arrested were later released to their units.

Every soldier arrested that night was charged with possession of marijuana because of a single marijuana cigarette found at the party, officials said at the time, citing information the Army received from the police. No one admitted to owning the cigarette, so police officers cited everyone with possession.

Soldiers who were younger than 21 were also cited with underage drinking. One soldier, Spc. Ronald Jenkins, was also cited with unlawful noise and hosting of minors.

After the arrests, "a number of soldiers specifically requested to be tested to prove that they weren't illegally using marijuana," Lavigne said.

As of Friday, "no action has been taken at the unit level, but as all of those actions would be administrative in nature, we wouldn't discuss them anyway," he said.

While the Army's investigation into the events of that night continues, commanders are looking at each soldier's case individually, Lavigne said.

"There was no mass reaction, there was no one-size-fits-all," he said. "Each situation was weighed individually, which is how it was supposed to be done. Some people probably expected a mass overcorrection."

It's too soon to say if the soldiers might be punished, Lavigne said.

"We had a number of soldiers that said they were in the wrong place at the wrong time," he said. "Whether or not they were doing the wrong thing will bear out over time. We'll find that out over the course of our investigation."
