Eighteen adults and two children were found stuffed under the floorboards of a truck entering the US earlier this week. A trained canine border patrol dog alerted to the tractor trailer and the subsequent inspection revealed the migrants hiding, packed tightly like sardines, in cavities under the flooring of the trailer. Temperatures are on the rise and US Border Protection says smuggling attempts like this have a high potential to turn deadly due to heat stroke/hyperthermia.
