A stranger allegedly stabbed a toddler in the face as she sat in her stroller at a Rhode Island school bus stop, years after he was accused of knifing two other children and found incompetent to stand trial.

The child’s fight for survival has brought renewed scrutiny into the suspect’s past, including an attack on two children more than two decades ago and repeated findings that he was incompetent to stand trial.

Nelson Blanco, 46, is accused of stabbing the 2-year-old girl and her mother Wednesday afternoon near Broad and Public streets in Providence, police said.

The mother was waiting with her daughter for her other children to get off a school bus when Blanco allegedly approached and made insulting comments, Providence Police Chief Oscar Perez said, according to WPRI.

Surveillance video showed the mother and daughter attempting to move away before Blanco grabbed the stroller and struck the child repeatedly, Boston 25 News reported.

A bystander tried to intervene, but Blanco allegedly attempted to stab that person before fleeing, according to the outlet.

Officers found Blanco hiding in the basement of a nearby home and recovered a knife from a panel box, police said. Authorities said he admitted to the stabbings during questioning.

"If I was on a side street, I would have killed them. Both of them," he said, according to the outlet.

No plea was entered during his Thursday appearance in Rhode Island’s 6th Division District Court. The court referred him to the public defender and requested an evaluation, according to court records reviewed by Fox News Digital.

His arrest brought back painful memories for Andy Lopez and Dave Belony, who told WPRI they were 6 and 7 years old when Blanco attacked them while they played in Lopez’s backyard on Sept. 27, 2003.

"I knew it was him, because I will always remember that face," he told the station. "My heart dropped, and it truly felt like my world had stopped." Court records reviewed by Fox News Digital show Blanco faced two felony assault charges and a charge of possessing a knife or firearm during a crime, stemming from the 2003 incident.

Multiple entries state, "Defendant Remains Incompetent." The case remains listed as "under review" in the court portal.

More recently, Blanco was found incompetent to stand trial in July in a separate domestic violence case, WPRI reported. A judge accepted a doctor’s recommendation allowing him to remain in outpatient treatment because he was considered unlikely to endanger the community or himself at that time.

Lopez and Belony said the earlier attack left them with injuries and trauma that have followed them into adulthood.

They told WPRI they were playing with Lopez’s brother when Blanco emerged from a shed behind the house where he had been living. "He didn’t say a word," Belony recalled.

"His face was blank and he was just staring at us." Belony said Blanco charged at him, trapping him near a tree. He curled into a ball and covered his head as Blanco stabbed him.

"My brother yelled at me to run, and I was trying to run but my body just froze," Lopez told WPRI. "He stabbed me twice in the eye — the first time it was blurry, and then the second time I couldn’t see anything." Both children were rushed to Hasbro Children’s Hospital. Their recovery took three months and included at least three surgeries each, they told the outlet.

Lopez was left permanently blind in his left eye, an injury he said derailed his dreams of becoming a police officer or truck driver. "Most of the opportunities I wanted to have in life are gone," he said. "I’m very grateful I’m alive, but my life is restricted." Belony said he was stabbed at least five times in his stomach, back and ribs and continues to struggle emotionally.

The men said learning about the latest attack left them devastated for the mother and toddler, and determined to speak out. "It’s frustrating for us, not only because of what happened to us, but because it has happened to others," Lopez told WPRI. "He was given a chance 23 years ago, and 23 years later, he did the same thing." "We want justice for the victims," Belony said. "What is it going to take for him to be held accountable for his actions?" Fox News Digital reached out to the Providence Police Department and the Rhode Island attorney general’s office for comment.
