As a wounded Mason desperately tried to scramble from the truck and fell onto the asphalt, Ellis allegedly stood over her and pumped additional rounds into her body at point-blank range to ensure she was dead immediately.

The investigation has since shifted from a search for a missing person to a high-stakes manhunt for a highly skilled and dangerous outdoorsman.

Following the double homicide, Ellis allegedly dumped his truck at South Beach and walked directly into the ocean fully clothed.

In a mind-bending twist, fire rescue crews actually intercepted him 900 yards offshore, but the killer gave a fake name and refused help before vanishing into the Atlantic near Riomar Country Club.

Police executed a series of search warrants at Ellis' southern Indian River County home, seizing an additional cache of firearms and digital devices currently undergoing forensic analysis.

Chief Curry noted that as an avid hunter, Ellis possesses the survivalist skills necessary to navigate the rugged Florida coastline and evade capture indefinitely.

Here's the chief again at the news conference.

The search has reached a fever pitch with cadaver dogs and high-speed Zodiac boats scouring the surf.

While authorities admit Ellis may have drowned, they are operating under the grim reality that a double murderer remains at large.

If captured alive, Ellis is facing a capital felony that could land him on death row.

A routine child custody exchange at a San Antonio, Texas YMCA dissolved into a scene of primitive violence after a scorned mother allegedly teamed up with her replacement's ex-boyfriend to carry out a calculated hit.

Melanie Sierra Gomez, 32, and Abel Rivas, 26, are facing felony aggravated assault charges after an ambush that left Oscar Javier Barbosa fighting for his life.

Investigators say the plot was a twisted alliance of exes where Gomez allegedly recruited Rivas, the former flame of Barbosa's current girlfriend, to settle a blood debt over a new pregnancy.

The trap was sprung at the Davis-Scott family YMCA on Iowa Street.

According to an arrest affidavit, Gomez lured Barbosa outside the facility via phone, leading him directly into the path of a knife-wielding Rivas.

Barbosa's current girlfriend was on the line during the attack, hearing the victim desperately plead, quote, "'Are you going to stab me over this?'

end quote, before the call cut to silence."

As Rivas allegedly went to work with a folding blade, Gomez did not just watch.

She reportedly became the muscle, physically pinning Barbosa against a car and dragging him back as he tried to run from the flurry of stabs to his stomach and arms.

Gomez, who was already on probation for making terroristic threats, allegedly taunted the bleeding father about getting his new girlfriend pregnant before Rivas hijacked the victim's car and fled.
