Katy Perry's ex-boyfriend Johnny Lewis, who starred in HBO series Sons of Anarchy, has been found dead.
The 28-year-old actor – who dated Katy for 18 months until March 2007 – is believed to have killed his 81-year-old landlady Catherine Davis before leaping to his death from his home in Los Angeles on Wednesday.
The upstairs of the building had been ransacked and a cat had also been killed.
Los Angeles Police Department Spokesman Andrew Smith said: "It's a terrible tragedy as far as we're concerned and we're digging into the bottom of it.
"He appeared to have died from some type of fall, either from the stairway, or from the balcony, or from one of the roofs.
"The best we're piecing together now is that it appears that some type of altercation occurred inside of the house resulting in the death of the woman.
"Then this individual ran outside, had an altercation with a couple of neighbours, ran back into the house and by the time we got here, he had fallen or had somehow died on the driveway."
Officers initially responded to a 911 call that a woman was heard screaming.
No motive for the killing is yet known.
Katy Perry is "devastated" about his death. Perry, who dated the Sons of Anarchy star for 18 months until early 2007 – is believed to have been partly inspired by her former partner throughout her career, but knew she had to break up with him at the time because he was a troubled soul.
A source told USMagazine.com: "She is devastated. She had to separate from him to get ahead and focus on her career. He was in trouble then and she couldn’t help him. A lot of her songs were partially inspired by him.
"I know The One That Got Away and Circle the Drain are partly about him, as well as Travis McCoy. But she was young and it was a time in her life she cherishes."
Johnny is believed to have killed himself by leaping off his home after beating his 81-year-old landlady to death.
