Police say an SUV involved in a collision that killed three children under the age of 10 and their grandfather this week, can still be used as evidence despite the fact that it briefly caught fire while in police custody.

The front grille of a Jeep that collided with a minivan in Vaughan on Sept. 27 caught fire at police headquarters one day later, prompting a visit from Central York Firefighters.

“The fire was quickly extinguished and the integrity of the evidence was not compromised,” York Regional Police Const. Andy Pattenden told CP24 over email.

Nine-year-old Daniel Neville-Lake, five-year-old Harry and two-year-old Milly died after the collision, along with their grandfather, 65-year-old Gary Neville.

Marco Muzzo, a 29-year-old King Township man, was arrested at the scene, located at Kirby Sideroad and Kipling Avenue.

He has been charged with 18 offences including four counts apiece of impaired driving causing death and dangerous operation of a motor vehicle causing death.

Sources have told CTV News Muzzo was driving at approximately double the speed limit at the time of the collision.
