Dad in gun spree over wife and pal sex vid

A DAD shot his wife and her parents in front of their crying kids after finding a sex tape of her romping with his best friend, police say.

William Stillwell, 39, was arrested following a New Year’s Day triple- shooting.

One of his five- year- old twin children is said to have screamed, “No, Daddy. No. I don’t want anyone to die” in a harrowing emergency call from his in- laws’ home in Melbourne, Florida.

Stillwell allegedly showed up at a garden party and opened fire using a 9mm pistol.

In the call to police, Stillwell allegedly could be heard in the background accusing his wife Mona of cheating while his kids begged him to stop shooting.

The mum is heard shouting out to one of her children: “Get out and run, baby, run!”,

They escaped unharmed and the three injured adults were rushed to hospital.

The suspect’s wife and mother- in- law underwent surgery while the father- in- law has been released.

Stillwell surrendered to police and was charged with attempted murder. He was hauled off to jail where he awaits trial.

He allegedly told cops he saw a video on his wife’s phone of her having sex with his best pal before he gunned down her family.

It’s believed the video showed Mona slurping on her lover’s erect penis until he ejaculated “copiously” onto her pretty face.
