MEMPHIS, Tenn. — Court records revealed the man accused of killing his 3-year-old has a violent and troubling past.

Josiah Patterson’s family tried warning police about his father before.

A report from November last year showed Kerra Brown was scared for her life.

Brown told police her ex-boyfriend, Terry Patterson, was “sending her threatening text messages.”

The messages said Patterson would hurt and kill Brown, according to the incident report.

Brown told investigators Patterson even made a comment about performing a sex act on her 2-year-old daughter.

However, no charges were ever filed.

“How can he do his son like that? That’s what went through my mind because when I left my son my son was breathing, he was talking,” Brown told WREG on Sunday.

Nearly a year after the threats, Josiah ended up dead with his father locked up for the crime.

Josiah’s mother was not the only one concerned about Patterson.

At least one woman that we know about told police Patterson messaged her underage daughter on Facebook “soliciting for sexual favors.”

The case was handed over to the Memphis Police Sex Crimes Unit.

WREG On Your Side Investigators dug deeper into Patterson’s two statutory rape convictions.

In the 1996 case, the victim told investigators Patterson picked her up outside of a school and had consensual sex.

However, the teen later discovered Patterson video recorded the intimate moments and wanted nothing to do with him.

Patterson did not like it and admitted to the teen’s following hand-written statement.

“He choked me really hard. He said if I didn’t do what he said, and he said he was going to kill me if I didn’t have sex with him,” the 17-year-old victim wrote.

Patterson will be back in court with a lawyer next Tuesday.
