Kwame Carpenter was taken into custody after a security guard at Fountain Valley Regional Hospital saw a suspect and car matching the description of the wanted man and his vehicle about 3:30 a.m. and notified a Santa Ana police officer who was at the hospital on an unrelated matter, said Fountain Valley police Lt. Rob Sweaza.
"The Santa Ana officer, in conjunction with Fountain Valley officers, went to the location on the southeast portion of the hospital campus and contacted Carpenter, who was inside his parked 2001 Lincoln Town Car," Sweaza said.
"When officers attempted to take Carpenter into custody, he refused to surrender and drove his car into a Santa Ana police car, damaging it," Sweaza said.
Carpenter then allegedly crashed the Lincoln into another vehicle and kept going.
"At that point a Fountain Valley officer fired two rounds at Carpenter as he fled the scene in his car," Sweaza said. "No one was injured as a result of the shooting."
Officers chased the car north on Euclid Street, where Carpenter abandoned the vehicle and ran into Mile Square Park "and into a small lake on the northeast corner of the park," Sweaza said.
"A Fountain Valley officer deployed his police service dog, (which) chased Carpenter into the lake, and the service dog bit Carpenter," Sweaza said.
"Eventually, Carpenter was taken into physical custody by officers," Sweaza said. "Carpenter suffered unknown injuries ... (from) the police dog, and was turned over to Anaheim police officers," Sweaza said.
No officers were injured.
The attack on the mother and child occurred in an apartment in the 2600 block of West Ball Road, Anaheim police Lt. Eric Trapp said.
Police were dispatched to the location at 12:10 p.m. Monday on a "felony assault in progress" call, Trapp said.
The victims, whose names were not immediately released, reportedly were stabbed, but investigators have not confirmed how they died. Police believe Carpenter was the father of the dead child and lived "in a common law relationship" the boy's mother.
