Ugo Fredette, who's accused of kidnapping his son last week, has been taken to a detention center in Saint Jerome.
On Friday, the 41-year old was transferred from Ottawa to a Quebec hospital after a suicide attempt while in police custody.
He and his 6-year old son were found west of Ottawa late last week.
The boy was fine.
Fredette's also charged with the murder of the boy's mother.
As well, police want to question him following the death of 71-year old Yvon Lacasse, whose SUV police say Fredette drove for part of the getaway.
Fredette has a court appearance scheduled for Monday.
