REDWOOD CITY, Calif. (MCT) — Pacific Gas & Electric knew its gas-line records were inaccurate and knew those errors could mean death or injury to the people who lived near its pipes yet chose not to fix the problem, according to testimony from a senior company engineer.

Senior Gas Engineer Todd Arnett, during a deposition on the hundreds of lawsuits stemming from the deadly 2010 San Bruno, Calif., pipeline blast, said he warned his supervisors that the company’s computer system for keeping track of the pipeline system was riddled with errors. But his bosses didn’t fix it; instead they told him to keep using it.
