TUCSON, AZ - A bee attack killed two dogs in Tucson, Ariz. The owner and his roommate say they've never seen bees act this aggressively.
"You can see blood on the wall over here."
That's what Lawrence Rios was shocked to see outside his east side home.
Blood from his dogs, who desperately tried to escape a vicious swarm of bees.
"They were just covered in bees. I can just imagine what they went through," said Rios.
Rios and his roommate Robby came home from biking and sensed something was wrong the moment they got out of his truck.
"I seen the bees and I wondered where my dogs were. They wouldn't come. I called for them and everything, they wouldn't come."
Both men walked to the yard but quickly had to turn back.
"We were attacked, both ran different directions down the street and they attacked us for maybe 200 feet and we couldn't even come near the house after that and then I had to check on the dogs so I came back," said Robby DeCesari, Rios' roommate.
Rios called 911 for help, knowing his dogs needed help.
Tucson firefighters arrived and sprayed foam in the area.
When the bees finally cleared out, they found both dogs unconscious.
"I rushed them to the vet and they were both dead. These were both 100 pound dogs. Big dogs," said Rios.
Rios adopted Gypsy from Pima Animal Care years ago.
"We went through a lot together and it's really sad. I'm heartbroken. She was my best friend."
He later adopted Atlas to be her companion, never knowing they'd both die together from a bee attack.
"One of my dogs is missing the claws on his paw, he had cut gashes all over his head trying to escape from the backyard to get away from the bees. And the other one was just very swollen."
As for where the bees came from, Rios had no idea a hive was hidden inside a brick wall behind his yard.
Rios says a neighbor sealed the hive, and speculates that's what caused the swarm to attack.
"Just leave the bees alone. Call a professional. Let them come out. Because it could be your kid that dies, and not a dog."
It has not been confirmed whether the bees were Africanized honey bees, commonly known as "killer bees."
