State College police are investigating a crash that injured a pedestrian around 2:25 a.m. Saturday, sending him to the hospital.

State College police Lt. Mark Argiro said 20-year-old Penn State student Roberto Baldizon Diaz was crossing North Atherton Street at the Mitchell Avenue intersection when a vehicle heading northbound hit him.

Argiro said the driver, Cherelle Douglas, 27, of Florida, was not charged, nor reported injured.

“It’s my understanding that she did nothing wrong,” Argiro said.

According to the accident report, Douglas tested negative for drugs or alcohol in her system, and was not driving at an unsafe speed, according to the accident reconstruction team.

Argiro said Douglas told patrol at the scene that she was driving north on North Atherton Street when Baldizon Diaz was crossing the road. The driver allegedly told police she never saw the man until the crash, due to his dark-colored clothing.

Baldizon Diaz was flown to Altoona Regional with head trauma, according to police. Police also said he was conscious by the time police and medics arrived on scene, where responders found him lying motionless in the south traveling lane on North Atherton Street near the curb.

Argiro said Baldizon Diaz was tested for drugs and alcohol, but results were not available. As of Saturday evening, he was transferred to a private room out of the ICU, according to the hospital.

Centre LifeLink and Alpha fire police assisted at the scene. North Atherton Street between Hillcrest Avenue and Cherry Lane was closed for several hours during the crash investigation.
