A 29-year-old man accused of drunk driving in a crash that killed three children and their grandfather will make a rare in-person appearance in Newmarket court today.

Marco Muzzo is expected to attend this hearing in person and his lawyer hasn't commented on the progress of the case.

The King Township man has typically appeared via video link or had his lawyer speak on his behalf.

Muzzo, of King Township has been charged with four counts of impaired driving causing death and 14 other counts related to the crash. He has yet to enter a plea.

On Sept. 27, six members of the Neville-Lake family were travelling in a minivan when the vehicle collided with a black SUV driven by Muzzo at the intersection of Kirby Road and Kipling Avenue, north of Kleinburg, just after 4 p.m. 

Daniel Neville-Lake, 9, his brother Harrison, 5, their sister Milly, 2, and their grandfather, 65-year-old Gary Neville were all killed. 

Neville-Lake's mother and great-grandmother sustained injuries in the collision. 

Muzzo last appeared in court via video link on Dec. 10 when his case was put over until today.

The children's parents have attended every one of Muzzo's court hearings to date.
