Red Sox employee, girlfriend die in car accident

Jack Lanzillotti, Red Sox manager of productions for game operations, and his girlfriend Jessica Campbell were killed in Boston's Back Bay when a vehicle that had just been in an accident rolled onto the sidewalk and struck them both on Saturday night.

Lanzillotti, 28, was pronounced dead at the scene, according to the Boston Globe. Campbell, 27, was taken to Brigham and Women's Hospital, where police said Sunday she died of her injuries.

Lanzillotti had been with the Red Sox for seven years. He produced videos on the scoreboard at Fenway Park and won a New England Emmy in 2011 for a piece he helped create about Jacoby Ellsbury's basestealing ability.

"Jack loved the Red Sox organization, and the Red Sox organization loved him," said Sarah McKenna, the club's vice president for fan services and entertainment, said in a statement. "He was our go-to guy, someone you counted on to handle a tremendous work load, and someone you relied upon to use good judgment no matter the urgency or the hour. We are crushed. We have lost a dear and dedicated friend."

Lanzillotti joined the Red Sox organization as in intern in 2007 before graduating from Boston University's College of Communications in 2008 and taking a full-time position.

"Jack has been an important, respected, and beloved member of our organization for the past seven years," Red Sox president/CEO Larry Lucchino said in a statement. "His poise under pressure and good-humored manner helped us deliver consistently outstanding results. We are all grief-stricken, and we send our deepest sympathies and condolences to Jack's and Jessica's families."
