In the warrant file, it's reported that the officer said there was "silence."
"Newly filed court documents bring up even more questions, an officer said she called Maze's cell phone number about 10:00 p.m. Tuesday night. Someone answered and the officer said there were gunshots, then silence."

But, Rita called her husband AFTER that at 10:25 ?? HUH???? ETA and failed to mention that she had been shot or had heard shots?
