Killer knifeman Steven Robertson posted a chilling message on social media just hours before he carried out his attacks on his ex-wife and step-daughter.
The 40-year-old stabbed Emma Coupland and Nicole Anderson to death before dying in a car crash as he tried to flee the scene.
The Record can reveal that police officers are scouring CCTV cameras after witnesses claimed Robertson, who split from Emma last summer, had been seen sitting in his car outside the hospital the night before the fatal stabbings.
Posting on Facebook just before he carried out his horrific attack, Steven lambasted his estranged wife and accused her of being a liar and cheat who had turned his children against him.
In the now deleted post, he wrote: “Well well well, I never thought you would turn the kids away from me.
"I'll no need a phone anymore.
"I never in my life after 20 years together thought you would do this.
“You keep saying what you won't because I don’t care anymore, the right people know the truth, that's all that matters to me.
"Thanks for all the people who told me stuff, there are some right good people out there.
"I am going to close my Facebook for good and I am not going to have a phone because I don’t need one anymore."
