A 2-year-old was raped by her father in a video he uploaded to the dark web, according to police.
The girl's father, 30-year-old James Lockhart, faces the death penalty if convicted of the horrific abuse.
US Homeland Security said the Florida father "posted a video of extreme sexual abuse of a female child [appearing to be less than 2-years-old[ by an adult male" in November 2017.
According to the Miami Herald, Lockhart also made posts on securely encrypted web pages detailing his sexual experiences with a young girl and boy, while asking for suggestions of things he could do and promising future updates.
Authorities managed to track Lockhart down through instant message service Kik and raided his home.
According to Homeland Security, the alleged paedophile's wife was shown footage of the horrific ordeal and was able to instantly recognise her baby daughter, her husband's hands, their couch and daughter's stuffed toy.
The 2-year-old girl and her twin brother were been taken into custody on the day of their father's arrest.
It is understood the suspect has made other postings to the dark web under a different username.
Lockhart faces numerous charges including capital sexual battery - which carries a death sentence if convicted.
