The accused teenage killer pleaded guilty to felony murder in the 2018 killing of a beloved Ventnor grandfather.
He was arrested in Atlantic City, after the Surveillance Center tracked him using the parked car.
In 2020, an appellate panel overturned then-Family Court Judge Susan Maven's decision to keep him in the juvenile system.
He pleaded guilty Thursday to first-degree felony murder, which is a death that occurs during the commission of another crime.
Delgado had allegedly escaped from a juvenile center at the time of the killing, lying in wait before shooting the man who was headed to work, and taking his car presumably to avoid riding his bike in the rain.
He faces 30 years in prison without parole under the plea agreement.
Delgado has had six birthdays since his arrest. His problems have continued while incarcerated.
He was charged with attacking a worker at the juvenile detention center where he was previously held before being moved to the Atlantic County Justice Facility at his request.
Juvenile defendants waived up to adult court can stay in a juvenile facility due to their age unless the state makes a motion to move them.
His mother, Susana Fischer, indicated he had his reasons at the time for wanting to be moved to the adult facility, but has declined to comment on those reasons.
When commenters on social media raised concerns about the then-teen's safety in an adult facility, Fischer said that her son "knows how to protect himself."
It appears instead he incurred more charges, and at least one injury.
Delgado had a brace on his left arm when he appeared in court in October.
His attorney told the judge her client's arm was broken and his elbow shattered. She said she asked the Atlantic County Prosecutor's Office to put in a request to have him moved.
Delgado was charged with aggravated assault on a corrections officer a month earlier, according to court records. It was not clear if that was the same time he was injured.
The incident that led to his injury was under investigation, Atlantic County spokeswoman Linda Gilmore told BreakingAC at the time.
Nothing was made public in that investigation.
Last month, Delgado was moved to the Cape May County jail — where he currently remains.
He is set to be sentenced in September.
