A 2-year-old boy was killed Thursday morning when he was attacked by his family's pit bulls.
Concord police Lt. Jim Lardieri said both police and animal control officers were called to a home in the 1700 block of Trail Creek Court at about 8:45 a.m. Thursday after receiving a report that a child had been attacked by dogs.
The boy reportedly wandered into the garage where the family kept their three pit bulls.
Once the toddler got in the garage, the dogs viciously attacked him, according to police.
Two adult relatives and one other young sibling were home at the time. They were not the boy's parents, but a grandmother and uncle.
Neighbors say an extended family lives in the home.
The boy was taken by ambulance to a hospital where he was pronounced dead, according to Lardieri.
Late Thursday all five dogs were euthanized. That included the two dogs who were not involved in the attack.
Police also arrested the boy's step grandfather, 52 year old Steven Hayashi. He was not home at the time of the attack, but faces child endangerment and possessing a mischievous animal that causes death or great bodily injury charges and is being held on $120,000 bail.
Contra Costa County Supervisor Susan Bonilla released a statement saying that the county's animal services department has no record of any complaints or previous problems involving the dogs.
