Abel Garcia Jr. is being held in the Ada County Jail on a felony charge of aggravated assault after Boise police say he intentionally drove his car into oncoming traffic on Five Mile Road Sunday afternoon and caused a head-on collision.

The driver of the other car is being treated at a Boise-area hospital for treatment of what police describe as non life-threatening injuries, according to reports.

Police have not provided any information about a suspected motive in the case but did say Garcia did not know the driver of the other car.

Garcia's sister, Sophia Bowman, told the Idaho Statesman Monday her brother would never hurt anybody intentionally and has been suffering from depression.

She also said it is possible Garcia was trying to switch radio and lost control of his car by accident.

"My brother is the most caring person I know ... he goes to extreme lengths to help people whenever he can," Bowman said. "He would never hurt anyone on purpose."

Witnesses told police Garcia, 28, was driving a car northbound on Five Mile Road, just west of Ustick Road, around 3 p.m. Sunday, when it looked like he intentionally swerved his car into the path of oncoming southbound traffic and hit another car, according to reports.

Garcia was not hurt in the crash. Police reports do not say if Garcia or the driver of the other car were wearing seatbelts. Police were able to develop undisclosed evidence that Garcia caused the crash on purpose, which is why he was charged with felony aggravated assault, officials said Monday.

Garcia will make his initial court appearance Monday afternoon. The crime of aggravated assault is punishable by up to five years in prison.
