After investigating, deputies said Jeffrey Stotler broke into his girlfriend's home before her dad shot him.
Authorities were called to the Bennet home around 2 a.m. Wednesday.
The wife of Michael Kinney, 51, called 911 to tell them her husband shot their daughter's boyfriend, Jeffrey Stotler, 21.
"Jeffrey Stotler attempted to gain entry into the home and eventually forced his way in," Chief Deputy Jeff Bliemeister said. "He was shot inside the confines of the Kinney's residence."
The Sheriff's office said the incident began while Stotler and his girlfriend, Miranda Kinney, 18, were driving back to Bennet from Lincoln.
Deputies said Stotler was driving at high speeds and made his girlfriend feel she was in danger.
When they got to the Kinney's home, Miranda got out of the car and was hit with the passenger side door while Stotler was backing up.
"Miranda went to the front door, attempting to gain the attention of her parents and was grabbed by Stotler," Bliemeister said.
Deputies said when her parents came out of the house, they could tell Stotler had been drinking and offered to take him home. They said Stotler took off in his car, but returned and broke into the house. That's when Kinney shot him.
When they got there, deputies found Stotler behind the Kinney's house with gunshot wounds to his abdomen and chest. He was taken to the hospital and Kinney was taken into custody.
In a strange twist, Kinney's own son, who works in corrections, helped place his dad under arrest.
Kinney will be in court next Friday. It's up to the County Attorney now to decide what he'll be charged with, if he's charged at all.
Stotler remains at Bryan West Hospital. The Sheriff's Office said he's also on probation for a domestic assault that didn't involve his current girlfriend.
Stotler is still in critical, but stable condition. Michael Kinney has been released on bail.
