The seven-year-old stepson of a man wanted for attempted murder in relation to an assault at a St. Catharines bank has died in hospital.

Niagara Police said officers responded to a call at 10:16 a.m. Friday after receiving a report that a child was in medical distress at a Queenston Street property.

The child, who has been identified as seven-year-old Nathan Dumas, was transported to hospital in critical condition, where he later died.

Minutes after police received the medical distress call, Const. Phil Gavin said the suspect entered a Royal Bank branch on Martindale Road just before 10:30 a.m. Friday morning and assaulted a female employee with a weapon.

The man fled the scene in what is believed to be a 2009 Pontiac Montana minivan, licence plate BYTE 392.

Police said the woman was taken to hospital in serious condition, but is currently stable.

Justin Kuijer, 43, of St. Catharines, is wanted for attempted murder.

The female victim and Kuijer were known to each other professionally, police said.

Dumas is identified as Kuijer’s stepson. It is unclear if there is a connection between Dumas and the female victim. The boy’s cause of death is not being released.

Kuijer is considered armed and dangerous. Anyone with information is being asked to call 911 or Crime Stoppers anonymously at 1-800-222-8477 (TIPS).
