It's something you never want to hear about, a former nursing home employee showing up at the building overnight with a gun.
Adams County Deputies said that's what happened at Timberpoint Healthcare in Camp Point, Illinois.
They said former employee is 39-year-old Bruce Gilker, Jr. was arrested.
They're still not sure what his plans were when he forced his way into the nursing home, but they said fast action by employees may be why no one got hurt.
"A former employee forced his way into the building at gunpoint. The staff responded immediately with the active shooter policies that they've been trained on," said nursing home administrator Andrea Lewis.
She said Bruce Gilker got in the building around 3:30 a.m. by threatening an employee with a gun, getting him past the locked doors.
Workers called 911 and put their lock down plan in place, keeping residents in their rooms and locking doors.
"The perpetrator was in the building approximately 20 minutes Adams County Sheriff's deputies arrived on the scene and took him into custody without incident," said Lewis.
Officials at the Adams County Sheriff's office said Gilker could be facing even more charges for what happened here at the nursing home.
"We're still investigating everything one we're looking at motive we're looking at why he was there what was all going on in his mind. Does he have access to more weapons all sorts of things," said Adams County Chief Deputy Rich Wagner.
He said incidents like these are an important reminder to be ready for things like this.
"Plan for it to happen," said Wagner. "Talk to your employees plan for it and train, have an idea where your exits are have an idea what you're going to do if it is to happen,"
Lewis said she's thankful her staff were able to execute their plan so no one was hurt.
"Thank you so much to the Adams County Sheriff's Office. Thank you so much to dispatch for staying on the line with my nurses, and also thank you very much to my midnight shift staff," said Lewis.
Lewis said no residents were aware anything was happening during the lock down.
Gilker faces charges of Aggravated Unlawful use of a Weapon, Possession of a Firearm without a FOID and, Aggravated Assault.
