The family of a Dallas police officer killed in a Hillary Clinton campaign motorcade is suing the city and former presidential candidate.

Senior Cpl. Victor Lozada died Feb. 22, 2008 while escorting Clinton during her presidential campaign trip to Dallas. Lozada's motorcyle ran up a sidewalk at the Houston Street viaduct, hit a concrete railing and was thrown from his motorcycle.

The suit, filed in Dallas County's 298th District Court this week, claims Clinton and her campaign "gave Dallas short and inadequate notice of the motorcade."

It also claims the city did not adequately train or prepare Lozada, who had recently become a motorcycle officer.

"The City of Dallas had not required any kind of run through, special training or a practice run for Officer Lozada or any of the officers," the lawsuit states.

City of Dallas spokesman Frank Librio said the city does not have a comment about the lawsuit.

The manufacturer of Lozada's helmet, Super Seer, is also listed as a defendant because Lozada's family claims the officer's helmet came off during the crash.

The suit does not specify an amount of monetary damages. The family is asking for a jury trial.
