I suppose if he pinned her down and made her drink two or three gallons of iced tea....... No. The theory doesn't work. That much tea would have made her as round and bouncy as a beach ball. When Michael goes to put her on her stomach, she bounces out the front door and they find her in the parking lot.
The medical examiner mentioned iced tea as a possibility, didn't he? That always made me wonder why he did not mention domestic violence as a possibility. A far more likely possibility by the way.
It seems, as far as this medical examiner goes, hearsay talk about iced tea consumption takes precedence over broken bones in an ex-ray report.
