SLIDELL, La. — The St. Tammany Parish Sheriff's Office has arrested a St. Bernard man who is believed to be connected to a murder that occurred Sunday in Slidell.
Police say 30-year-old Derick Fehn was found around 8 p.m. on Monday night at a home in St. Bernard Parish. He will be booked into the St. Bernard Parish Jail while he awaits extradition to St. Tammany Parish.
Fehn is charged with one count of Second-degree Murder, two counts of Attempted First-degree Murder, and one count of Obstruction of Justice.
According to police Fehn allegedly drove to the 2000 block of Old Spanish Trail on Sunday afternoon. Investigators say Fehn had been in a days-long feud with his significant other and her sister.
When Fehn showed up on the scene, the sister, the victim, and their small child exited the home and walked toward Fehn’s vehicle. Fehn then shot at the three.
The sister and the child were not injured, but the sister’s 30-year-old boyfriend sustained gunshot wounds. He was transported by medical personnel to an area hospital, where he died from his injuries.
