The number of people who die after trying to cross the border into the United States is higher this year. According to the medical examiner, she’s performed autopsies on two people this morning alone.

Hot summer sun is taking its toll on dozens of people attempting to cross the US-Mexico border.

“Your body starts to shut down, your body stops sweating, and eventually it could lead to death.”

Two people have died in the last 24 hours, and many more may be next.

“The two individuals we had this morning died due to heat stroke. They were recovered in ranch areas.”

One of the victims is a woman, which she says is rare. Fire department officials say she was found on a ranch near Bruni, Texas and was only 28 years old.

“Our EMS and paramedics have responded to the rural areas of Webb County where they have seen the most severe cases of heat related injuries.”

In 2007, most of the deaths were drownings.

In 2008, extreme heat killed many trying to cross the border.

On average about 40 people will die in one year here in Webb County after trying to enter the United States.

Already this year, twenty people have died.

“Typically we don’t see this many this early in the year. The numbers are up.”

Stern says two have died from rattlesnake bites, which is also rare.

With summer only beginning, she says it’s too early to tell just how many lives will be lost to the effects of the sun.

Stern also says that not all deaths are those of Mexican nationals. She says people from Honduras and Guatemala, including two from Nicaragua, have been victims.

Fire officials say it's important for everyone to remember to keep hydrated and if you just aren't feeling well after being out in the sun, call 911.
