Mexico is no stranger to violence and law enforcement authorities say it's only getting worse.
"The violence has escalated in Mexico", Cameron County Sheriff Omar Lucio said.
The root of the problem, power, drugs and money.
"Every large and small law enforcement agency here on the south western border knows that the violence is because of the drugs coming into the United States", said Lucio. "And the money and the weapons and the stolen vehicles."
Stories making recent headlines include 18-year-old Jonathon Torres.
Torres who was a freshman at the University of Texas at Brownsville was killed following an incident where cartel members allegedly hijacked a bus in Mexico.
Then there is the case of 30- year- old David Hartley.
Hartley was allegedly gunned down last Thursday by Mexican Pirates while jet skiing on the Mexican side of Old Gurerro Lake.
Another case in Brownsville involved the deaths of two men who were allegedly gunned down by cartel members.
"I believe this incident here was one of those things that happened somebody was trying to get these people so they tried to run into the United States", said Sheriff Lucio.
"And of course they are not familiar with all the areas here and they were being chased and ended up close to Paredes Line", said Lucio.
Sheriff Lucio tells Action 4 News says he believes the double homicide in Brownsville was an insolated incident.
The Sheriff goes on to say people should not be afraid, but remain alert.
"We don't want to alarm people we want them to be cautious, we want them to be careful ", said Lucio.
Sheriff Lucio adds, local and federal authorities are in constant communication with each other.
He says his officers are vigilant, and the man power is there if need be.
