(CNN) — ALAMO HEIGHTS, Texas — Valerie Redus has spent much of her time crying, since her son Cameron was killed by a campus police officer in Texas last week.

For now, she and her husband Mickey are withholding judgment about who was at fault for his death — their 23-year-old son or Cpl. Christopher Carter, who shot him Friday.

“We wish that everybody else would do the same, would reserve judgment until facts are known,” Mickey Redus told CNN’s George Howell late Tuesday.

The official account has left the Reduses in disbelief.
