Anchorage police have charged a woman with stabbing her 3-year-old son at a Muldoon residence Tuesday afternoon, with the child remaining in critical condition.

According to APD spokesperson Jennifer Castro, 40-year-old Tracia Jordan-Sainte faces one first-degree count each of attempted homicide and assault, in the incident on the 200 block of Muldoon Road. Officers were first called to the stabbing at 1:19 p.m.

“Police and medics responded to the scene; the child was transported to a local hospital in critical condition,” Castro wrote. “Jordan-Sainte was taken into custody as police conducted a preliminary investigation of the assault.”

Castro didn't have any details beyond her statement immediately available Tuesday night.

Police arrested Jordan-Sainte at a residence at the Safe Harbor Inn. The inn provides transitional housing for homeless individuals and families.

Castro says responders are aware of at least one stab wound to the victim, but cannot say for sure whether there were more.

"There’s always what’s visible to us, what we can see," Castro said. "We did see an apparent stab wound of the child, but there’s always what doctors, medics find in addition -- so we don’t know if there are more, if there is just one at this time."

Medics responded to the scene and transported the child to a local hospital in critical condition. Officers at the scene credited Safe Harbor Inn personnel for their assistance in the investigation.

"The staff here have been incredibly cooperative in helping us trying to understand the events that took place," said Sgt. Amanda Fisher.

A brief statement issued Tuesday afternoon by Safe Harbor Inn's board chair, Tom Newins, expressed condolences for the victim.

"The board of directors and employees of Safe Harbor Inn are concerned for the safety of the child injured today, and are cooperating fully with the (Anchorage) Police Department in their investigation of this tragedy," Newins wrote.

Safe Harbor Inn resident Raymond Felix expressed shock at Tuesday's events.

"It's a little frightening because I've got two kids of my own, and wherever I go they go," Felix said. "And then this happened -- it's scary."

Robert Maxwell says he was visiting a friend at the Safe Harbor Inn when he witnessed the stabbing. Later that day, he recalled what he saw of the suspect.

"She was emotionally wrecked," Maxwell said. "She was having a hard time talking."

Maxwell says the event saw his worst fears realized about what had occurred.

"I said I felt like something bad had just happened, and 'I hope that she didn't just hurt her kid' is actually what I said," Maxwell said. "And it turned out to be that's what happened."
