Authorities believe the man shot the mother of his two children at least six times with a small-caliber handgun about 12:30 a.m. in Riverside. He fled after taking her to a hospital, authorities said.
About eight hours later, about 2:45 p.m., authorities shot tear gas into the vehicle, but the man still did not surrender. Authorities deployed a K-9 unit and eventually took the man into custody.
He was taken to hospital for minor injuries and will be released to Riverside County authorities when his treatment is complete, authorities said.
The woman is expected to survive. The nature of their relationship is unclear.
