Rosa was reportedly not the driver but participated in the carjacking Friday morning.
Rosa told police that the driver of the car swerved the stolen vehicle to dodge a police officer and lost control of the car before crashing.
The two men responsible for a carjacking that led to the deaths of three children are reportedly in police custody.
Around 9:30 p.m. Sunday night, police announced that they were questioning two "persons of interest" with regard to Friday's fatal carjacking in Tioga. Reports this morning say charges are expected to be filed against the two men soon.
Police Commissioner Charles Ramsey has said he is "confident" they have the men responsible in custody and said a "manhunt" is not needed at this time, ABC reported.
According to ABC, one suspect, accompanied by his mother and pastor, turned himself in to police Sunday night. He reportedly gave information to police leading them to the second suspect, who was taken into custody near 6th and Cambria streets, where he was homeless and living in a shed.
The two men are wanted in connection with the Friday morning carjacking that left three children dead.
Just after 11 a.m., two men carjacked a 45-year-old woman’s Toyota 4Runner, forcing her into the backseat.
While traveling at a high rate of speed, the driver lost control of the vehicle and crashed into a sidewalk fruit stand at Germantown and Allegheny avenues in Tioga, killing three children and injuring two adults, including the children's mother.
The suspects fled on foot.
The children killed in the accident, Keiearra Williams, 15, Thomas Reed, 10, and Terrence Moore, 7, were siblings. Their mother Keisha Williams, 34, is in critical condition.
The children were running the fruit stand as part of a fundraiser for the Eagles Wings Evangelistic Church at 17th and Tioga.
