Rose Helen Kewlani, 52, of West Columbia, South Carolina, was fatally shot while inside a vehicle on the westbound side of Interstate 26 near exit 82 (Prosperity) on a Monday morning. An autopsy was scheduled to determine the exact cause of death.

The suspect was identified as 45-year-old Wilfrido George Luna, also of West Columbia. After the shooting Luna reportedly ran across the interstate, allegedly carjacked a tractor-trailer during his escape, and prompted lockdowns at Mid-Carolina High School and Mid-Carolina Middle School that lasted under 30 minutes. Following a brief pursuit and a standoff, Luna was arrested in the parking lot of the Mid-Carolina Country Club and charged with murder; he is being held at the Newberry County Detention Center. The South Carolina Law Enforcement Division is assisting the Newberry County Sheriff’s Office, and authorities have not released a motive or described any relationship between Kewlani and Luna.

Was anyone in the Prosperity area that morning a witness to the shooting, the movements on Interstate 26, or the alleged tractor-trailer carjacking?
