(AP) — Authorities in Sedgwick County have arrested four people in a shooting that left a woman dead and her husband critically injured.

The couple was rushed to a Wichita hospital Friday night after they were found suffering from gunshot wounds outside their home in Valley Center, which is north of Wichita. The Sedgwick County Sheriff’s office said 53-year-old Melissa Bluml died Saturday. Her husband, Roger Bluml, remains hospitalized in critical condition.

The sheriff’s department says three men and a woman have been taken into custody.

Sheriff’s Capt. Greg Pollock also says investigators expect to meet with prosecutors this week to determine if charges will be filed.

Pollock says authorities don’t expect any more arrests, but the investigation is ongoing.
