A 3-year-old boy was found dead in a septic tank after playing in a backyard over the weekend, police say.
The Pierce County Sheriff’s Department told FOX 13 Seattle that the young child – who was a Lakewood, Washington, resident – was pronounced dead after being removed from the tank at around 3 p.m. on Monday. Authorities were alerted to the incident at around 2:20 p.m. that day.
Investigators believe that the boy was playing with his 4-year-old brother and six-year-old neighbor before he fell into a neighbor’s septic tank. The child reportedly removed the tank’s lid before falling in.
His brother quickly went inside to alert their grandmother, who then called the police.
