MIAMI-DADE COUNTY, Fla. — A man is fighting for his life after being beaten and stabbed during an armed carjacking that investigators believe is connected to a series of violent crimes across southwest Miami-Dade Thursday night.
The suspect, Alejandro Martinez, 33, has since been arrested, the Miami-Dade Sheriff’s Office confirmed Friday.
According to MDSO, the first attack happened shortly before 8:45 p.m. Thursday near Southwest 67th Avenue and 40th Street.
Deputies said a man was beaten, stabbed and robbed of his vehicle during an armed carjacking.
Miami-Dade Fire Rescue personnel transported the victim to a local hospital in critical condition.
According to Detective Angel Rodriguez, Martinez fled the scene in the victim’s vehicle, but the violence did not end there.
A short time later, deputies responded to two additional armed robberies and carjackings. The first was reported near Southwest 137th Avenue and 56th Street, followed by another at a gas station near Southwest 157th Avenue and 88th Street.
Surveillance video obtained from a nearby 7-Eleven at Miller Drive and Southwest 137th Avenue shows one of the victims stumbling into the store while holding his neck and suffering from visible injuries to his arm. Other people inside the store appeared to come to the man’s aid.
Omar Orozco, who was working behind the counter at the time, told Local 10 News that the victim in that case told him he had been robbed.
“What the guy said who was bleeding said that it happened in the parking lot. He took his phone and his wallet,” Orozco said.
The victims in those incidents were hospitalized, but are in stable condition, Rodriguez said.
As deputies searched for the suspect, they located one of the stolen vehicles in the area of Southwest 152nd Avenue and 72nd Street and spotted a person matching the description of the suspect running away from it, Rodriguez said.
According to Rodriguez, Martinez was taken into custody after deputies chased him on foot.
“After interviewing the subject, detectives learned in addition to the armed robberies/carjackings, the individual was also involved in two additional incidents (Midwest and Hammocks Districts) where he beat the victims, causing them to be transported by MDFR to area hospitals (unknown conditions),” Rodriguez said.
Jail records show Martinez is facing a slew of charges that include attempted felony murder, armed robbery with carjacking, armed robbery with a weapon, aggravated assault with a deadly weapon/
As of Friday, he was being held at the Turner Guilford Knight Correctional Center, where his bond was listed as “to be set.”
The investigation remains ongoing.
