STOCKTON, Calif. -- A rock was thrown through the front window of the home of Pete Morelli, an NFL official, and police said Friday they have no suspects in the case.
Morelli, a ninth-year official, made a controversial call last Sunday during the Pittsburgh Steelers' divisional playoff win over the Indianapolis Colts. He incorrectly overturned a tumbling, fourth-quarter interception by Pittsburgh safety Troy Polamalu, according to Mike Pereira, the league's vice president of officiating.
Morelli is also a high school principal, and it's unclear whether the rock-throwing incident was related to his school job or his NFL affiliation.
"There are no leads to follow up on," said Stockton police spokesman Pete Smith. "We don't have any idea of the motivating factor."
The grapefruit-sized rock was thrown through a front window of Morelli's home about 10:30 p.m. Monday, Smith said. Neither Morelli nor his wife, who was also home at the time, was injured.
NFL spokesman Greg Aiello called the incident "regrettable" and said the league has been in contact with the police department to see "if this was a random act or related to football."
Morelli's ruling allowed quarterback Peyton Manning to lead an Indianapolis touchdown drive but ultimately did not affect the game's outcome. Pittsburgh held on to win after a missed field-goal attempt by the Colts in the closing seconds and will visit Denver in this Sunday's AFC title game.
