Mr Beirouti, who was known to police, was father to a five-month-old baby, Nine News reported.
“My heart is so broken,” his partner, Argina Baker, posted in a tribute on Facebook, “I will always and forever love you…missing you so much.”
“I haven’t the words right now…..Rest In Peace my love, till we meet again.”
Detective Acting Sergeant David Miller said the impact of the tyre-deflation devices, known as ‘stop sticks’, could have contributed to Mr Beirouti’s loss of control.
“As the vehicle’s been travelling down Stud Road, its front right tyre is deflating, so it’s going to give you less control of that car,” Sergeant Miller said.
“In this section just behind me, there is a slight dip in the road which tends to lead to making the vehicle move towards the centre median.
“So he’s gone off the road onto the grass, unable to retake control, and he’s then slid … on an angle, glanced off one tree, straightened up, and then pretty much [gone] head-on into the large tree, where the momentum of the car spun it around.
“It sort of peels it open like a tin can.”
Major Collision Investigation Unit detectives are investigating the circumstances surrounding the Rowville crash, as are Professional Standards Command, who will have oversight of the investigation given the death occurred following contact with police.
A report will also be prepared for the Coroner.
Anyone who witnessed the incident, or who may have dashcam footage, is asked to call Crime Stoppers on 1800 333 000 or www.crimestoppersvic.com.au.
