INDIANAPOLIS » Police have released two photos of a suspect in the fatal shooting of the pregnant wife of an Indianapolis pastor as they hope to draw tips from the public.

The photos, taken from a home surveillance video, show a person walking in the neighborhood where 28-year-old Amanda Blackburn was killed. Police revealed they had the footage Friday, but didn’t release the images until Monday.

More than 2,000 people attended a memorial for Blackburn on Sunday in nearby Whitestown. It was coordinated by four churches, including Resonate Church in Indianapolis, where her husband is a pastor, and a church in South Carolina, where the couple belonged before moving in 2012 to found Resonate.

Blackburn died Wednesday at a hospital after the shooting Tuesday morning. She recently had announced she was pregnant.
