A 15-year-old teen boy has been arrested by police as a second suspect in a murder on Picton Avenue on early Tuesday morning.
The teen faces a charge of aggravated assault and second-degree murder.
Officers were originally dispatched to reports of an assault in progress in the area of 100 Picton Avenue just after midnight on Tuesday, March 3.
When officers arrived they located two female victims outside near the street.
Paramedics transported both to the Thunder Bay Regional Health Sciences Centre for further treatment of their injuries. One victim died from those injuries, the other remains in the hospital.
20-year-old Brianna Lynn Netemegesic was already charged with aggravated assault and second-degree murder.
The name of the second accused is being withheld in accordance with the Youth Criminal Justice Act.
He is expected to appear in bail court on Wednesday.
A post-mortem examination of the victim is taking place in Toronto today. The investigation is ongoing.
