ABU DHABI -- The former husband of the American teacher killed in an Abu Dhabi mall is speaking out.

"One just needs to look at the video. The images of that bathroom … knock you out,” says Paul Ryan, Ibolya Ryan’s ex husband.

Paul Ryan says he thinks Dalal al Hashemi, the 38-year-old Emirati woman identified as the suspect, acted alone.

“After seeing the video of how she was captured and what was in her car, she had everything there … She could easily have done this all by herself,” he says.

Ibolya Ryan had been in the bathroom when the suspect stabbed her six times with a kitchen knife.

Police say Hashemi was targeting anyone who looked foreign.  They say she also planted a homemade bomb outside an American doctor's home (that was found and dismantled in time.)

The case remains under investigation.
