Man charged with murder pleads ‘not guilty,’ nearly 5 years after deadly shooting in SE Wichita

WICHITA, Kan. (KWCH) - Approaching five years since one man was killed and another injured in a southeast Wichita shooting, the case against the man accused of pulling the trigger is progressing after a final decision on his competency.

Twenty-two-year-old Teviuan (also recorded as Teviaun) Sebastian was in court on Wednesday for a hearing at which he pleaded “not guilty” to charges connected with the September 2021 death of 66-year-old Greg Cummings. A 37-year-old man was also wounded at the scene on South Mission, near Lincoln and Oliver.

After years of hearings on the matter, a Sedgwick County District Court judge concluded in March that Sebastian’s case can proceed.

“The Court, after reviewing the report from Osawatomie State Hospital dated February 6. 2026, hearing the statements of counsel, considering all evidence. examining the Court’s file, and being duly advised in the premises, finds that the defendant is competent to stand trial,” the order read.

Sebastian entered his plea to one count each of first-degree murder, attempted first-degree murder, aggravated battery and criminal discharge of a firearm, after waiving his right to a preliminary hearing in the case, court documents show.

Records show that Sebastian is due back in court on July 29 for a pretrial conference. He’s in the Sedgwick County Jail, held on a $1 million bond.
