This is the horrifying moment a mother appears to push her autistic son into a canal in what police say was her first attempt to kill him.

Patricia Ripley, 45, faked Alejandro Ripley’s abduction after trying to drown him twice, with witnesses rescuing the boy from a Florida canal the first time, and the second attempt ending in the boy’s death, officials have said.

Alejandro was autistic and nonverbal. He was found floating in a Miami canal Friday.

Ripley is facing attempted and premeditated murder charges.

Footage obtained by Univision shows Ripley walking with Alejandro, stroking his head, then appearing to push him into the water. She then runs off screen before returning with neighbors who saved the boy.

In an interview, Fernandez Rundle said Ripley apparently tried to drown her son at Kendall Acres Condominium complex, where the footage was taken, but nearby residents heard yelling and rescued him.

Then, Fernandez Rundle said, Ripley drove her son to another canal at the Miccosukee Golf and Country Club.

‘Unfortunately when she took him to the second canal, there was no one there,’ Fernandez Rundle said. ‘She tried it once, and people rescued him. He was alive. He could have stayed alive. She intended, from all the facts of the case, to kill him.’

The boy’s father, Aldo Ripley, broke down in tears after a bond court hearing Saturday. Between sobs, he said: ‘We love Alejandro, and we got aggrieved with whatever they said about my wife. It’s not real.’

He added: ‘I don’t agree with whatever they’ve said about my wife.’  He told 7News: ‘The only thing I’ll say is that we love our life.’

Alejandro’s brother wrote online: ‘For those who know my family, brother, mother, father, you guys know. Thank you and God bless.’

Miami-Dade State Attorney Katherine Fernandez Rundle said Patricia Ripley is facing attempted and premeditated murder charges and being held in jail with no bond.

Fernandez Rundle said an autopsy was being done on the boy Saturday to determine if he had other injuries or perhaps had something toxic in his system. She said no decision has been made yet on whether prosecutors will seek the death penalty.

Miami-Dade police department says the mother first claimed she was ambushed by two black men who demanded drugs and took her cellphone, tablet and son, before fleeing Thursday night, prompting an Amber Alert in the area south of Miami.

The boy’s body was pulled out of a golf course canal early Friday as police continued to interrogate the woman.

An arrest affidavit says she provided ‘conflicting statements,’ and finally was confronted with testimonies of witnesses and video footage showing the first attempt to push the boy into the canal.

The document says she recanted her story and admitted she drove to another site and led the boy into a different canal stating ‘he’s going to be in a better place.’
