T-shirt tourniquet save

Bronx cops used a T-shirt as a tourniquet to save a woman's life after her ex butchered her with a kitchen knife while her young children cowered in her apartment Monday morning, police said.

The former beau, Wilson Rojas, 32, later tried to hop a flight to the Dominican Republic — but Port Authority police stopped him at Kennedy Airport Monday night.

Rojas forced his way into the 24-year-old woman's apartment on Allerton Ave. near Olinville Ave. in Allerton at about 8:22 a.m., grabbed a kitchen knife, and repeatedly stabbed her in the chest and arm, cops said.

He then ran off and left her to die, cops said

Two 49th Precinct officers, Steve Yankowski and Justin Sokol, responded to the scene at about 8:45 a.m., and found the woman on her back in the hall, a mass of blood spreading underneath her.

“(Sokol) started rendering aid with a T-shirt cause that's what we had at the time, basically using it like a tourniquet," Yankowski told reporters.

The woman was in stable condition at Jacobi Medical Center.
