Only days after arresting a driver who ran over and injured four cyclists out for a group ride, the Austin Police Department arrested Austin resident Merrick David Isaacks for shooting and hospitalizing cyclist Alonso Solis-Mata earlier this month.

The 19-year-old claimed he was trying to "blow off steam" when he allegedly fired his shotgun from a car at Solis-Mata at midnight on June 7.

Solis-Mata was rushed to the hospital, where he was treated for "unknown injury to his back, shoulder, and head after he was struck by what appeared to be a shotgun blast," and "pellets from the shotgun blast [that] had entered the victim's brain stem," according to the Fox News report.

In an affidavit, a witness—who says he was forced at gunpoint to drive the car during the assault—said Isaacks "turned his entire body toward the passenger side door and lifted the shotgun to the window as if he was aiming at something and fired one shot."

That shot, the witness believes, was the one that hit Solis-Mata. Following that, the two continued driving, with Isaacks shooting into the air a few times.

Isaacks has been charged with two counts of aggravated assault with a deadly weapon; his bail has been set at $250,000.
