Four teens are under arrest after a brawl in a Bronx park on Tuesday night ended with one teen dead and another wounded. 

Police said it happened during a fight between groups of young men.

Andrew Ansah, 18, Jordan Williams, 18, and a 16-year-old and 15-year-old have all been charged with murder, manslaughter, gang assault and criminal possession of a weapon in the killing of 14-year-old Angel Mendoza. 

What police say happened

Mendoza's father said his son went to Williamsbridge Oval Park at around 6 p.m., just after his mother had made him dinner, and didn't see him alive again.

"He said, 'Bye,' and left to go to the park with his friend," Miguel Mendoza said through a translator.

Police say at around 7:30 p.m., a dispute broke out between two groups of teens that started as a verbal argument but quickly turned into a brawl that lasted about 15 minutes.

Officers found Mendoza on the ground with stab wounds to the abdomen. He was rushed to Jacobi Medical Center in critical condition but died shortly after. Police sources said a 17-year-old who was stabbed in the abdomen and shoulder got himself to Montefiore Hospital and is listed in stable condition.

Police sources say investigators recovered a knife and a gun not far from where a memorial of candles now sits. 

After learning of son's death, father says "I went crazy"

Angel Mendoza's mother was so overcome with grief, she could barely stand, but his father said on Wednesday that just last month he had a conversation with his son about being careful with whom he spends time.

"When my wife called saying they had stabbed my child, I went crazy. I went to a few hospitals but he wasn't there," Miguel Mendoza said, adding he was later informed of what had happened by police.

He said his son loved basketball and music, and hanging out with his friends.

"I don't know who did it, but I want justice," his father said.

A friend who was given parental permission to speak to CBS News New York said he was supposed to meet Mendoza in the park.

"He invited me to come and I was just like, 'No, I can't.' My mom wasn't gonna let me," the friend said. "I woke up at 7 in the morning. My parents came and woke me up saying that Angel died and at first I never believed it. That's something that wouldn't happen to him. He's a nice kid. He was always laughing."
