On the 84th anniversary of the murder of Arcadia police officer Albert E. Matthies, a ceremony was held by the Arcadia Police Officers Association in his honor. Matthies is the city's only police officer killed in the line of duty. A memorial plaque at Foothill Boulevard and Northview Avenue commemorates Matthies' sacrifice and a small plaque marks his grave site at Live Oak Memorial Park in Monrovia. Matthies was shot on July 18, 1927 and died the day after. The shooter was Frank Miller.
