Lavar McKiernan, 34, who was to be booked on charges of felony driving under the influence, felony evading causing injuries, and attempting to harm a police dog, was moved to Tri-City Hospital in Oceanside, where he was being held under guard Sunday morning.
According to authorities, just before 1 a.m. Sunday, Carlsbad police Officer Samantha Alexander tried to stop McKiernan at Carlsbad Boulevard and State Street, near the Army and Navy Academy, after his vehicle reportedly nearly crashed into three parked cars
McKiernan drove off with Alexander in pursuit, rear-ended a vehicle and ran into a telephone pole before heading into the Buena Vista Lagoon west of Carlsbad Boulevard, about a half-mile from where the chase started.
Other Carlsbad police officers, assisted by an Oceanside police dog and the San Diego Police Department's Able helicopter, pursued McKiernan to the lagoon, where he was spotted hiding in about 4 feet of water.
After being given several opportunities to surrender, police went into the water along with the dog to arrest the suspect.
McKiernan attempted to drown the dog, who was not injured, three times before he was arrested.
