Seattle police looking for father who threatened to kill referee at middle school girls soccer game

Seattle police are looking for a man who allegedly got so angry at a middle school girls soccer game last weekend that he threatened to kill two referees.
According to police reports, one referee worked during the first half of the Saturday match between two Seattle middle school teams and then sat out the second half of the game in the stands for. The ref reported that it was at that point the suspect first approached him about a a call made during the game, although he remained cordial during that discussion.
During the second half of the game the other referee awarded one of the teams a game-winning penalty kick. This apparently enraged the man, who reportedly began hurling slurs at both referees, and told one of them that he would kill him "when you walk out that stadium door."
The incident was not reported to the police until after the game, when one of the referees called police from his home to report the incident. The victim told officers he did not know the suspect, but believed he was the parent of a girl on one of the teams.
Seattle police have not revealed the names of the two middle schools involved in the game but have asked for anyone with information about the incident to contact them.

In July of this year a pair of dads at a children's soccer game in London, Ontario became involved in an conflict between their daughters. One of the men punched the other repeatedly, resulting in medical attention for a face injury to one, and an assault charge for the other.
