Sergio Brown appears to surface in Mexico with bizarre rant

Ex-NFL player Sergio Brown, who went missing after his mother was found dead in a creek near her Illinois home, appears to have surfaced in Mexico in a bizarre video posted to Instagram, claiming he thought his mom was on vacation and that he had been kidnapped by law enforcement.

The former 35-year-old player is believed to no longer be missing Tuesday after he was spotted in a bizarre Instagram story shared on “intplayerwithapassport,” which appears to be a burner account for the player.

In the video, the former New England Patriot player addressed the news that his mother Myrtle Brown, 73, was found dead near a creek behind her home.

Sergio Brown said he thought his mother was on vacation and that he had been kidnapped by the FBI and the Maywood Police Department.

He also makes several claims of “fake news” before going off on an incoherent rant, during which he accuses the Maywood Police Department and the FBI of kidnapping him twice from his home.

“They kidnapped me twice from home. The Maywood police department,” he said before his words became muddled and unintelligible.

“It had to be the FBI or the Maywood police,” he says to the camera as loud music blares in the background. “I thought my f–kin’ Momma was on vacation.”

The video was allegedly taken and tagged with a location of Mexico City before being deleted and reposted without the location, Deadspin reported. His whereabouts still remain unclear.

Even before he and his late mother disappeared, Sergio Brown had been acting out of character for months, their neighbor Carlos Cortez told CBS 2.

Cortez says he last saw the mother and son on Thursday, but police told him they spotted something unusual on a ring doorbell camera.

“They see him taking out the trash, and they see him have a bonfire where he burnt all her clothes,” Cortez said.

The abnormal behavior has apparently been typical for Sergio Brown in recent months, Cortez said, adding that he spoke to the slain woman’s relatives who said her son had been “out of his mind.”

Police are aware of the video purportedly shared by Brown on Tuesday.

“Maywood Police Department detectives are aware of a video that has surfaced on social media in relation to Mr. Sergio Brown, who is still considered a missing person and are also looking into its authenticity,” Maywood Police Department’s Public Information Officer Carmen Rivera told The Post.

Sergio Brown is known for his career in the NFL spanning from 2010 to 2016 when he retired from professional football.

The former safety appeared in 94 games for the New England Patriots, Indianapolis Colts, Jacksonville Jaguars, and Buffalo Bills.

He and his mother were reported missing by family on Saturday, prompting a search throughout the village of Maywood that ended in the discovery of Myrtle Brown’s body.

He has not been named a suspect in his mother’s death, which has been ruled a homicide.

A rep for Sergio Brown declined to comment when reached by The Post.

The Maywood Police Department is actively investigating the case and has asked anyone with information regarding Sergio Brown’s whereabouts to contact their anonymous tip line at 708-450-1787.
