LAS VEGAS (AP) - A 43-year-old man has been arrested in the shooting deaths of a Las Vegas couple in their home.
Joseph McManus was booked on murder charges Saturday into the Clark County Detention Center.
Police say he phoned them Friday night to report that he had found his parents dead inside their Cottontail Lane home.
Officers arrived to find a man and woman with apparent gunshot wounds.
The man was pronounced dead at the scene, while the woman died after being taken to a hospital.
Police say initial reports indicated the husband shot his wife, then turned the gun on himself.
But investigators say they later uncovered evidence that links McManus to the shootings during an altercation inside the home.
