A Franklin man was arrested Sunday after he allegedly attacked a sheriff’s deputy.

Johnson County Sheriff Doug Cox says that at about 2:30 p.m. on Sunday, deputies were called to the 5300 block of Birch Lane, in

Greenwood, on a report of a man acting erratically. According to the report, the man, Christopher Derringer, 46, was pounding on the back door of a home belonging to his mother’s neighbor. When the owner of the home went to investigate the noise, he told authorities that he saw Derringer walking away. The man then reportedly yelled at Derringer to stay off of his property, which, he says, resulted in Derringer throwing a flower pot in the homeowner’s direction and Derringer’s dog biting him on the leg.

When deputies arrived, they say that Derringer approached one of them in a threatening manner, asking if he wanted a fight. Authorities say this behavior continued, even as Derringer’s mother and girlfriend were physically trying to restrain him. The deputy says that Derringer began walking toward his mother’s house, taunting law-enforcement to shoot him. The deputy followed Derringer, asking him to calm down and talk to him. As Derringer was attempting to go inside of his mother’s house, the deputy says that he ordered him to stop, which he says angered Derringer and resulted in him walking up to the deputy and repeatedly chest-bumping him. The deputy says that he then handcuffed Derringer. As he turned the suspect around, Derringer allegedly kneed him in the groin, twice.

Once Derringer was put in a police car, deputies say that they spoke with his mother and girlfriend. Both allegedly told authorities that Derringer was not in his normal state of mind. Deputies also say that the pair told them that Derringer went to house on Birch Lane to “find the answers.” The mother and girlfriend also allegedly told deputies that Derringer has threatened “suicide by cop” in the past.

When jail officers arrived on the scene to take Derringer in to custody, deputies report that he yelled at the neighbors, threatening that he would be “coming back to get them.” The Sheriff’s Department says that Derringer is facing preliminary charges of Resisting Law Enforcement, Battery on a Law Enforcement Officer and Intimidation. Deputies also say that a Victim Notification Form was completed so that the neighbors would be notified whenever Derringer is released. Deputies say that they also encouraged the neighbors to apply for a protective order against Derringer.

Animal Control is investigating the dog bite. The whereabouts of Derringer’s dog was not released.
