Sergio Brown Enters Not Guilty Plea In Connection To Mother's Murder

Ex-NFL star Sergio Brown has pleaded not guilty in his second court appearance since he was arrested in connection with his mother's death.

Brown was picked up by authorities and charged with first-degree murder and one count of concealment after his mother was found dead near a creek less than 100 yards from her house.

On Wednesday, the 35-year-old appeared before a judge and pled not guilty to the murder charge and concealment of a body. The former New England Patriots player is set for another hearing in court on January 24, per reports.

The former NFL star was arrested in October after he was deported from Mexico, where he was seen partying while authorities were searching for his mother, Myrtle.

Sergio and Myrtle's whereabouts first caught the attention of authorities when his brother Nick took to Instagram to announce that his brother and mother were missing.

"Folks, my mom Myrtle Brown and brother Sergio Brown are missing. I'm not waiting another hour. Please share! If you see them or one of them, please let me or the Maywood Police Office know!!" the announcement read.

A missing person's report was put up, and a neighbor of the Brown family revealed, "Her family knocked on the door and was looking for her because they put out a police report because she was missing for 72 hours. So, we tried to help them as much as possible."

Unfortunately, just a day after Nick's announcement, the 73-year-old was found dead near a creek. She suffered injuries related to an assault and her death was declared a homicide by the Cook County Medical Examiner’s Office.

A neighbor said of the late matriarch, "Myrtle, she was an outstanding woman, and I'm hoping she's in the right place and she's with God. I never would've expected this in a million years."

Amid his mother's absence and eventual passing, Sergio was found partying in Tulum, Mexico, and sharing erratic social media posts on his burner account. In one post, the Buffalo Bills alum denied claims of his mother's death.

"Fake news. It has to be the FBI that came into my house on Bob Marley’s death day, with the 511 haze and gas — unwarranted," he ranted. "They kidnapped me twice from my home. The Maywood, Ill. Police Department… it had to be the FBI or the Maywood Police. I thought my momma was on vacation."

In an earlier post, Sergio, who partied with scantily clad women while in Mexico, made light of the missing persons report filed by the police by referencing the 2003 children's film "Finding Nemo."

"Just keep swimming, just keep swimming," he said repeatedly. "What the f---? Missing? They ain't never seen 'Finding Nemo'? What the f--- is going on? This is traumatic. Lucky, I don't have to say a joke. You … what the f---? Just keep swimming."

The authenticity of the bizarre videos was confirmed by the authorities via a statement: "Maywood police spokesperson Carmen Rivera said in an email Tuesday, acknowledging police were aware of the videos and were investigating. Rivera did not immediately return messages Wednesday seeking an update."

An arrest warrant was issued and on October 10 and the former football safety was arrested in San Diego while re-entering the US from Mexico. Per sources, Mexican authorities were aware of Serio's whereabouts since September 19 and collaborated with US officials to deport him after his arrest warrant was issued.

It also didn't help that during the extradition flight from Mexico City to Tijuana it was reported that the Illinois native caused a stir and was threatened to be removed by the plane's captain.
