The father, a resident of Eslov in southern Sweden, admitted to police he forgot to drop his son off at daycare May 7 and did not notice when he arrived at work that the boy was still in the car. When he got back to his car, the 2-year-old was still in the back seat, unresponsive.
The daycare center acknowledged the boy's mother was not notified the child had not arrived, which is supposed to be standard practice.
The father admitted to manslaughter in a negotiated settlement of the charges against him, The Local.se reported Tuesday.
He was spared both imprisonment and a fine.
"If all parties are in agreement on the punishment, then we choose this path because it costs much less and does not involve the courts," Mats Svensson, the chief prosecutor, told the news agency TT. "Put simply, you could say that the suspended sentence is a warning."
