LOVELAND, Colo. — Family and friends will remember the life of an RTD security officer who was shot and killed while on duty in Lower Downtown Denver last week.

The Denver Police Department said Scott Von Lanken was shot “execution style” on Tuesday night while helping to give directions to two women near Union Station.

A service will be held at 10:30 a.m. Monday at Resurrection Fellowship Church in Loveland. His family said he wasn’t just a security officer, but also a husband, father, former police officer and pastor.

He is survived by his wife, Shellie, and two children.

Shellie Von Lanken said she wants her husband to be remembered as someone who loved to help people.

Investigators believe Von Lanken might have been killed because of his RTD guard uniform by a man described as having radicalized Muslim beliefs.

The alleged shooter, 37-year-old Joshua Cummings, has been charged with first-degree murder. He is due back in court March 3.

The Denver Muslim community said it warned the U.S. Department of Homeland Security about Cummings late last year. The FBI has yet to comment on the case.

A memorial fund to help support Von Lanken’s wife and two children has been established through the Rocky Mountain Law Enforcement Credit Union.

It’s under Scott Von Lanken’s name on the credit union’s website or by calling 303-458-6660.

A co-worker at RTD also set up a GoFundMe account for the family.
