Newly released 911 calls capture desperate attempts to save two men after gunfire erupted outside a Port St. Lucie home on Southeast Rivergreen Circle, leaving one caller pleading for help as a wounded man faded in front of her. Multiple callers contacted dispatchers shortly before 3:30 a.m. July 19 after hearing repeated gunshots near Southeast Rivergreen Circle.

One caller repeatedly urged one of the wounded men to remain conscious. "Breathe, baby, please," she said.

Officers responding to Southeast Rivergreen Circle found 24-year-old Carl Loubeau and 22-year-old Juliun Stokes suffering from multiple gunshot wounds. Both were taken to hospitals, where they later died. The most significant call appears to have come from 20-year-old Dwayne Walker, whom investigators identified as the man who returned fire after Loubeau allegedly shot Stokes.

"Somebody shot my cousin, and I shot back," Walker told a dispatcher. Walker also repeatedly told officers that the guns had been dropped and said he did not want any trouble.

Port St. Lucie Police Chief Leo Niemczyk said Stokes and several friends had gone bowling with Loubeau's girlfriend earlier that night. When the group returned to the home and realized they were locked out, the woman called Loubeau and asked him to bring a spare key. Police believe Loubeau became jealous when he arrived and saw his girlfriend with Stokes and Walker.

Investigators said Loubeau approached Stokes as he stood beside the open drivers door of a Ford Mustang and opened fire. Walker, who was near the rear of the Mustang, drew a lawfully carried handgun and returned fire, striking Loubeau. Investigators determined Walker acted in self-defense and said he will not face criminal charges. Detectives are continuing to review forensic evidence, phone records, toxicology findings and autopsy reports before formally closing the investigation.
