01/20 MIAMI (UPI) -- The mother of a 15-year-old girl who was one of three people stabbed to death in the aftermath of Hurricane Andrew lashed out verbally at the National Guardsman charged in the slayings. "I'd kill you personally, you pig! Do you know what you have done to my family and friends?" Judy Diaz screamed at the defendant, Steve Coleman, at a court hearing Tuesday. Coleman is charged with killing Diaz's daughter Regina Rodriguez; Ronny Quisbert, 20; and Andrew McGinnis Sept. 29 after a night of bar- hopping. Coleman, 24, of Tampa was a member of the National Guard contingent helping with hurricane relief at the time of the slayings. He said he acted in self defense. He was charged with three counts of first-degree murder and one count of sexual battery on Rodriguez. During the court appearance Tuesday, prosecutors charged Coleman with another felony, attempted sexual battery on McGinnis. "May God have mercy on your soul," Diaz told Coleman as she stormed out of the courtroom. The victims were stabbed inside a car parked at Florida International University. The sexual assaults took place after the stabbings. Coleman told police the three tried to rob him after giving him a ride.
