The Texas teen charged with fatally stabbing high school football star Austin Metcalf raked in nearly $200,000 for his legal defense in a matter of hours — after posts impersonating officials spread fake news about the killing, including painting the victim as a violent, drug-addicted bully.

Frisco Police Chief David Shilson warned the Dallas suburb that online trolls are trying to sow discord over the racially charged case — which shocked the nation after Metcalf’s family said he died in the arms of his identical twin brother after a very brief altercation with Karmelo Anthony, a student from a rival high school.

“Beware of those taking to social media to deliberately spread misinformation, hate, fear and division,” the chief said.

Meanwhile, Anthony’s family has hired two hot-shot Dallas lawyers who made names for themselves fighting headline-grabbing racial justice cases. 

Anthony, 17, told officers he killed Metcalf, also 17, in self-defense, according to cops, and his father echoed that in an interview with The Post last week. 

In a statement Monday, the lawyers said, “Karmelo and the entire Anthony family are sincerely saddened that a life was lost and offer their condolences to the family of Austin Metcalf.”

Meanwhile, the donations are continuing to pour in, with more than 5,400 people donating $185,000 as of Monday night on GiveSendGo — a fundraising platform that also raised money for Daniel Penny after he was arrested for the 2023 subway chokehold death of Jordan Neely. 

The Anthony family set up the “Help Karmelo Official Fund,” claiming a “false, unjust, and harmful” narrative is being spread about the slaying.

The fundraiser money, which is on track to blow past the $200,000 mark, seems to be mostly from small donations of $10 to $50.

“Good job standing up for yourself young man!” one recent donor commented.

“Isaiah 54:17 no weapon formed against you shall prosper and every tongue that rise up against you God shall condemn,” wrote another.

Police say Anthony pulled a knife out of his backpack and stabbed Austin Metcalf in the chest when Metcalf tried to make him leave his high school team’s tent at a track meet.

Anthony is in the Collin County Jail on a $1 million bond and a charge of first-degree murder.

The donations come as a flurry of conspiracy theories have gained traction online based on fake posts purporting to be from authorities in Frisco — including one that claims Anthony was sucker-punched and badly beaten during a fight with Metcalf, and another that Metcalf died of a drug overdose. 

Local officials blasted both claims as fake.

Cops said the FBI and local officers are investigating the fake posts.

But Frisco City Councilman Brian Livingston said residents are mostly staying above the flurry of conspiracy theories

“This is a much bigger deal on social media. I don’t think social media represents the city of Frisco,” Livingston told The Post.

“I think the city of Frisco has a history of handling things like this. We are a united community. It is taken seriously, but I think people are mostly concerned about the two families and focused on getting through this,” he added.

The money from the fundraiser will help the family retain two top Texas attorneys with a history of taking on racially charged cases, including negotiating a settlement for a 14-year-old girl manhandled by a cop at the 2015 “McKinney pool party” incident.

“Karmelo, like all citizens of the United States, is entitled to a fair and impartial legal process; we are committed to ensuring that Karmelo’s rights are indeed protected throughout each phase of the criminal justice system,” said Clark and Cole in a statement.

His lawyers are seeking to lower Anthony’s “excessive” $1 million bond and convince the Collin County district attorney to make “a better determination” of the charges, they said.

Kim Cole and her firm K. Cole Law represented black teen Dajerria Becton after a viral video from McKinney, Texas, showed a cop slamming and pinning her to the ground at a pool party.

Cole managed to win a $148,850 settlement for Becton from the McKinney police department and the officer, who resigned.

Billy Clark of the Clark Law Firm became a professional mediator after a 20-year career in the Air Force.

In a statement, the pair of attorneys directed people to the Anthony family fundraiser, but they also emphasized that a previous GoFundMe page claiming to be set up by Karmelo himself was fake.

The bogus GoFundMe page, which has been taken down, had claimed Karmelo was “jumped” and that Metcalf smashed his phone, among other salacious details.
