Moments after a man fired a shot into the back of Brienna Campos' head, she calmly explained her plight to a 911 dispatcher.
Two armed, masked men stormed her home on Bernadino Drive before dawn, yanked the three residents from their beds and shot them one by one in the back of the head, killing 19-year-old Alex Zaldivar.
"We didn't see him [Zaldivar] move, so I'm pretty sure he got a clean shot in the head and he's dead," Brienna Campos told the operator. "I can only think that they [the shooters] are probably linked to the people that robbed us last time."
The information contained in the 911 call made the morning of the Sept. 10 that gives new insight into the moments following the deadly attack. The call was recently released to the Orlando Sentinel in response to a public-records request.
Brienna Campos told dispatchers that seconds after the suspects ran out the front door, she and her brother ran out the back door, hopped a fence and banged on a neighbor's door for help.
Their head wounds left a bloody trail that marked their path.
"We saw them go out the door on foot, but I'm sure they probably had a vehicle somewhere down the road," Brienna Campos said when asked if she saw where the suspects went after the shooting. "I don't see them sticking around for too long after they had three gunshots go off in my living room."
Brienna Campos, 20, and Zaldivar were scheduled to testify the following day against two men accused of committing a home invasion at their house May.
Just before the victims were shot, the suspects asked if they were the same people involved in the earlier home-invasion incident, court records show.
During the May incident, the men rushed into the home in the middle of the afternoon, asked for drugs and cash. They ransacked the house, stealing electronics and cell phones.
Zaldivar, Brienna Campos and two others were in the home during that incident. Remington Campos, 23, was not home at that time.
Orange County deputies and Ocoee police were able to track down the suspects by using a cellphone tracking application and arrested 27-year-old Bessman Okafor and 26-year-old Nolan Bernard at a home in west Orange County.
The victims' parents believe the men who stormed the house on Sept. 10 were there to kill the witnesses and prevent them from testifying against Okafor and Bernard at the trial the following day.
Okafor, who was out of jail on bond, was being monitored by a radio-frequency device. Records show he was out of his home during the time of the murder. Bernard has not left the Orange County Jail since his arrest in May.
Police have not charged anyone with the deadly home invasion, but they have arrested several of Okafor's family members on various charges, including witness tampering. Okafor was arrested a day after the deadly shooting for violating the conditions of his pre-trial release.
New information also shows that the Campos' home on Bernadino Drive was burglarized twice in October 2011. The first time the suspect pried open a back door using a crow bar and stole a flat-screen TV, an X-Box game console and controller, according to a police report.
Residents suspected it was a former roommate who had recently been kicked out or one his friends. A dog lives at the house, and police suspect it was someone familiar with the animal and the home.
Three days later, someone attempted to break into the home again but was unsuccessful. Ocoee police records indicate both burglary cases are inactive due to a lack of leads.
