WICHITA, Kan. (KWCH) - More than five years since one man was killed and another injured in a southeast Wichita shooting, a resolution to the case is in sight.

Court records show that 23-year-old Teviuan (also recorded as Teviaun) Sebastian, the man charged in connection with the September 2021 death of 66-year-old Greg Cummings and the injury to a 37-year-old man at the scene of the shooting near Lincoln and Oliver, pleaded guilty last week to second-degree murder, attempted second-degree murder and aggravated battery.

The plea agreement comes more than half a year after Sebastian initially pleaded not guilty to charges of first-degree murder, aggravated battery and criminal discharge of a firearm. The initial plea in March followed a Sedgwick County district court judge’s conclusion that Sebastian was competent to stand trial.

The now 23-year-old’s guilty plea on amended charges of second-degree murder, attempted second-degree murder and aggravated battery moves the case to the sentencing phase.

The plea agreement calls for the murder and attempted murder charges to run consecutively and the aggravated battery charge to run concurrently with the time served for second-degree murder and attempted second-degree murder. The criminal discharge of a firearm charge was dismissed.

Court records show Sebastian’s sentencing is set for Jan. 8.
