Alex Minassian appeared in court on Tuesday where he was charged with 10 counts of first-degree murder and 13 counts of attempted murder after the deadly van attack in Toronto, according to The Toronto Star.
Minassian, 25, appeared briefly in court wearing a white jumpsuit while handcuffed in the prisoner's box.
He gave his name briefly but showed no emotion while he listened to the charges listed against him.
Minassian will appear in court again via video on May 10, but he needs to find a lawyer and due to the severity of the charges, the justice of the peace said that he was required to detain the accused.
The suspect was also ordered not to have any contact with the 13 attempted murder victims and when asked if he understood, he responded, "Yes."
The court document did not identify the names of the murder victims, only referring to each as an "unknown person."
The document did include the names of the attempted murder victims.
Court records showed that Minassian did not have any criminal record before these charges.
Toronto police said they would update the media on Tuesday afternoon.
Minassian is accused of purposefully driving his rental van on the sidewalk in order to strike pedestrians along the busy Yonge St. in Toronto on Monday afternoon.
Ten people were killed and fifteen remain in the hospital.
The suspect later abandoned the van but got into a brief standoff with police on Poyntz Ave. just south of the scene of the crime, which was caught by an eyewitness video where he yells at the officer to "shoot me in the head" after claiming he had a gun in his pocket.
Const. Ken Lam was the officer on the scene and arrested the suspect.
