KANSAS CITY, Mo. (AP) — The families of three people killed earlier this year outside two suburban Kansas City Jewish facilities are planning community events to mark the first anniversary of the slayings.

The Kansas City Star  reports plans for the event in April include a faith walk and songwriting to commemorate the April 13 deaths of William Corporon, Reat Griffin Underwood and Terri LaManno.

Corporon and his grandson were fatally shot outside the Jewish Community Center of Greater Kansas City in Overland Park, Kansas, while LaManno was killed at a nearby Jewish retirement home.

Wednesday’s announcement was timed to coincide with the preliminary hearing for the man accused of the shootings, Missouri resident Frazier Glenn Miller Jr. The hearing was postponed for an evaluation to determine if Miller is competent to stand trial.
