Peoria Unified School District Bus Aide Arrested on Sexual Abuse Charge

On Wednesday, Peoria police arrested a say a Peoria Unified School District bus aide on abuse charges.

Following a Peoria Police Department investigation, 66-year-old Marco Chinchilla of Sun City, Arizona.

Chinchilla was on administrative leave after an incident where he didn’t put a seat belt on a passenger. At that time, investigators became aware of a separate incident.


Peoria Police say Chinchilla allegedly “inappropriately touched” a passenger on the bus.  Police documents say video showed an incident on Jan. 13 during which Chinchilla was seen trying to unsuccessfully cover surveillance cameras inside the bus.

He was then seen sitting in front of an 18-year-old student, who functions at the level of an 8- to 10-year-old, for about 20 minutes. The video showed him interacting with the girl and repeatedly moving his hands.

Chinchilla said he didn’t remember why he covered the cameras and told police the girl was acting inappropriately.

However, in an interview with the victim, officials were told that the “weird guy” had “touched her ‘private parts’” and told her he “loved her.”

Records show Chinchilla denied ever touching the victim inappropriately.

Police say Chinchilla has been a bus driver for 20 years and had been working on the current bus, which transports special education students, for the past two months.

Chinchilla was booked into jail for one count of sexual abuse and one count of vulnerable adult abuse.

The investigation is ongoing. If anyone has any additional information regarding this incident, they are encouraged to contact the Peoria Police Department at 623-773-8311.
