Long Island mom charged with smashing 14-year-old girl in the head during high school spat

A furious Long Island mom allegedly got mixed up in an argument between her daughter and a 14-year-old classmate — and wound up bashing the youngster in the head with a huge Stanley water cup until the teen was bloody, cops said.

Tony Monroe, 35, was busted after allegedly flipping into a rage when her 15-year-old daughter “began exchanging words” with the victim outside Brentwood High School around 11 a.m. Tuesday, Suffolk County police said in a release.

That’s when Monroe — who claimed she was at the building to complain about bullying during summer school — allegedly smashed the younger teen, leaving her with a gash to the head that required 17 stitches.

“Her mom just came in and started beating me with the cup,” the victim, identified as Madison Evans, told WABC’s Eyewitness News. “I took my head because I saw blood dripping. I took my head and I saw blood all over my hands.”

Witnesses said Monroe grabbed the container and smashed the victim in the head several times before a school security guard jumped in and tackled the raging mom to the ground, News12 Long Island said.

That’s when cops showed up and busted her.

“We are aware of the incident that occurred yesterday during dismissal involving two students and a parent,” Brentwood Superintendent of Schools Wanda Ortiz-Rivera said in a letter to parents.

“The safety and well-being of our students is always our highest priority, and this type of behavior is unacceptable and will not be tolerated in our schools,” she added.

In court Wednesday, Monroe faced a judge as her lawyer claimed it was her daughter who was being bullied — the reason Monroe was at Brentwood High for a meeting that day.

“As a mom you’re supposed to diffuse the situation and take your daughter away to see what’s going on, instead of attacking a kid with a cup,” Tyleen Smith, Evans’ cousin, told ABC 7.

“She could’ve died. Anything could’ve happened to her, more than just being hit over the head and having 17 stitches,” Evans’ guardian Shameakca Forney, told the outlet.

Monroe was released without bail but ordered to wear a monitoring ankle bracelet and was issued an order of protection to keep her away from the battered teen.
