Newly released video appears to show the Florida woman accused of killing her son with autism pushing the boy into a canal — in what authorities say was a first, but thwarted, murder attempt.

The shocking surveillance footage, obtained and aired by Univision on Sunday, seems to show Patricia Ripley pulling 9-year-old Alejandro along the bank of a Miami canal, looking around — and then shoving him into the waters before running away.
