"The story of Rod Bradway -- it broke my heart. And the story of Officer Renn -- it just made me angry. Because here's another officer, a 22-year veteran of our force and this is how it ends," Crystal Sutherlin said.
Sutherlin never knew Officer Renn, but the news of his death hit home.
"This man was a good man. I have neighbors just like this man that go and do it day in and day out. And I was very angry with our city for coming to this point," Sutherlin said.
That is why she created the Facebook page. In only 24 hours, more than 6,000 people pledged to take part in the movement.
At Fusek’s True Value Hardware store, the shelves where the blue lights sit were empty Tuesday evening.
"We don't sell a lot of them, but we definitely felt a difference today. They bought up everything we had," owner Steve Fusek said.
A recent addition of four blue lights now sit on top of Officer Renn’s squad car as part of a growing memorial.
"It's just such a sad situation when an officer falls like this. My heart goes out to the family, and we just wanted to come and pay our respects. That's why we're here," Terry Dilk said.
Anyone looking for a blue light can buy one at most major hardware chains. Fusek said he will order extra blue bulbs in his next shipment.
Sutherlin said people have reached out to her on Facebook from as far away as Texas and New Mexico and have pledged to display blue lights in support of IMPD.
The Fraternal Order of Police will hold a special prayer vigil Wednesday night in support of the Renn family and the safety of Indianapolis police officers. All members of the community are invited to attend.
The prayer service will be held at Indianapolis FOP Lodge #86 at 7:30 p.m. and it will end at 8 p.m. with a blue light vigil service.
