Update (Jan. 11, 2016)-- Ashley Johnson was sentenced to three months of home detention in this case.

Original story:

INDIANAPOLIS, Ind. -- A woman posing as a nurse has pleaded guilty to making false statements regarding healthcare and could face several years behind bars.

Ashley Johnson was working for less than a month this past April at Clearvista Lake Health Campus in Indianapolis. According to court documents, Johnson was using the nurse license number of another woman who was also named Ashley Johnson and was a registered nurse.

Johnson was hired in early April to work at Clearvista, where authorities say on one occasion she gave the wrong medication to a patient.

In a statement, Clearvista Lake Health Campus Executive Director Tammy Tinsley said, “A person who identified herself as Ashley Johnson applied for a registered nurse position at our health campus in early April. Prior to her start date, we received completed background check form (which includes confirmation of active licensure) which showed all items clear, and no concerns.”

After Clearvista was tipped off by one of Johnson's references, she was suspended and then fired. The facility also filed a complaint with the Indiana Attorney General's office.

Court documents also show Johnson told Clearvista she had worked as a nurse at another Indianapolis facility since 2009. She also told Clearvista she attended school at Medtech College, but college transcripts revealed she had never graduated.

Johnson pleaded guilty in federal court to one count of making false statements regarding healthcare and could face up to five years in prison.
