A pit bull attacked and killed a man who was trying to help the dog's ill owner in a home in East Wheeling, W.Va., authorities said.

Wheeling police and other emergency responders were called to the home late Sunday night regarding a dog attack and had to force their way into the residence, where they found both victims.

One victim was badly injured; the other person was unconscious. Both were taken to local hospitals, where they were pronounced dead, police said. Their names have not been released.

Wheeling police Lt. Phil Redford says police believe the dog's owner suffered a heart attack and that the other man was attacked by the dog as he tried to resuscitate the owner.

Animal control officers removed the pit bull from the home and it has been quarantined.

No further information was released.
