An officer with the Tulsa (OK) Police Department who was severely wounded in a shooting during a traffic stop late last month is reportedly showing signs of improved heath.

Officer Aurash Zarkeshan was critically wounded during the incident and Sergeant Craig Johnson, died of his wounds on Tuesday.

Captain Richard Meulenberg told on Wednesday that Zarkeshan’s health has slightly improved and he's responding to doctors' commands but did not elaborate further.

The suspected gunman—identified as 32-year-old David Anthony Ware—was arrested following a search that lasted more than seven hours.
