ALBUQUERQUE, N.M. (KRQE) – More than two months after a Bernalillo County Sheriff's Office deputy was involved in a deadly crash, an investigation found his reckless driving was partly to blame. Now, a district attorney will decide whether that deputy will face charges.

The crash happened in August near Edith Blvd. and Alameda. Deputy Lassley initially told APD investigators that he was trying to catch up with a car he'd already tried to pull over, that driving dangerously and without plates. He said the driver, later identified as Alexandria Gerard, hit her brakes causing him to rear-end her. That's when her car propelled into a wall and killed her. "I don't see a turn signal. I don't see anything. The vehicle just seems to slow down abruptly, and I, I hit the back of it," said Deputy Lassley to APD investigators. Now, a new report concludes the deputy's actions played a part in that crash. According to APD investigators, Lassley was driving 70 MPH in a 25 MPH-zone five seconds before the crash. Newly obtained home surveillance video shows just how closely the deputy was following Gerard without lights or sirens. The crash happened right when the cars left the video frame. According to APD's report, Lassley was following the car too fast and too closely to expect it to safely stop for another traffic stop. The investigators determined his actions met the definition of "reckless driving" but stopped short of saying it was vehicular homicide. The report stated at most, Gerard committed misdemeanor traffic violations prior to the deputy's engagement. Deputy Lassley had his own idea of why Gerard hit the brakes in the first place. "Well, I think that she intentionally slowed down to where I would be struck by the vehicle to cause my to disable my vehicle," said Deputy Lassley to investigators. But the report said there is no way to know what caused Gerard to brake or if she even knew it was law enforcement behind her since there were no lights or sirens. The report also points to other factors that contributed to her death including her speed, no seat belt, an airbag that didn't deploy properly, and loose tools in her car that hit her in the head. The Bernalillo County District Attorney's Office said they will not take on this case to avoid any conflict of interest because they work so closely with APD and BSCO. A spokesperson for the DA's office said they are reaching out to other DA's to take up the case and determine whether criminal charges should be filed. BCSO said its internal affairs department has a copy of APD's report and is now conducting its own administrative investigation. A BCSO spokesperson said the agency will not comment on APD's report until their own internal investigation is complete. In the meantime, Deputy Lassley will remain on paid administrative leave.
