Junior's father curses suspect, as new testimony reveals what happened in car after teen's stabbing

THE BRONX (WPIX) -- The father of Lesandro “Junior” Guzman-Feliz screamed and cursed at one of the five murder suspects in court Thursday, after hearing new testimony of what happened in a getaway car, after his 15-year-old son was fatally stabbed last June outside a Bronx bodega.

“You're a f--king piece of s--t,” Jonaiki,” Lisandro Guzman yelled at Jonaiki Martinez Estrella, as the Murder 1 suspect sat at the end of the defense table. “You're stupid.”

The grieving father had just heard testimony from a Bronx detective, who quoted a man called “Witness A” in the case.

Witness A reportedly told the detective that he was in one getaway car with Martinez Estrella and Jose Muniz.

“Witness A had stated Jonaiki told him he stabbed the kid in the neck,” the detective said.

The brutal neck wound, which Junior can be seen clutching in various surveillance videos, is the wound that killed the teen, who was just finishing his sophomore year in high school.

People around the world were horrified to see Junior stumble back into the bodega, with the gaping neck wound, only to be turned away and directed toward St. Barnabas Hospital up the street.

Junior collapsed at the hospital's security booth and bled to death.

Detective Flores from the 48th Precinct also quoted Witness A talking about suspect Jose Muniz in the car.

“As he was holding the machete,” Witness A reportedly said of Muniz, “He said, 'You see this? If you tell anyone what happened, you know what will happen to you.'”

PIX11 is working to confirm the identity of Witness A.

The detective said Witness A told the cop he was a member of the “Bad Boy's” gang who hung out with the “Sure” set of the Trinitarios.
