Philadelphia councilman-at-large Jack Kelly (far left in photo above) spearheaded the effort to bring Lojack to the city.

“Lojack Safetynet has already saved the lives of two Philadelphians,” he said today, “and long after I retire I can take solace in knowing that this technology will save the lives of numerous Philadelphians for years to come.”

Police officials say that 359 officers in the city have been trained in how to use the tracking equipment.

After the six-month trial period, the service will cost $30 a month.  Payment plans are available.  For more information, caregivers can go to safetynetbylojack.com or call 877-4-FIND-THEM.
