The officers jumped the fence and put themselves between the teen and the dogs, in an attempt to stop the attack. The dogs attacked the officers, and they in turn fired their weapons at the dogs, police said.

The teenager was rushed to Parkland Memorial Hospital but later died.  One officer also received injuries from a dog bite, but was treated and later released.

The owner of the house, Guillermo Lorenzo, told CBS 11 he suspected the teen was “up to no good” and that his dogs were only protecting the property.
