Indiana Pastor Speaks of His Heartbreak Over Pregnant Wife's Murder

— -- The Indiana pastor whose pregnant wife was fatally shot in what authorities say was a home invasion spoke out for the first time about his heartbreak.

"It’s really hard to sort through all of the emotions of what we’re feeling about all this," Davey Blackburn told ABC News today. "We’re confused. We don’t understand why. We’re angry. We’re not really sure what to do."

Investigators have said that they believe Amanda Blackburn was shot in the head when a burglar broke into the Indianapolis home she shared with her husband, their young child and their dog. Police say that a suspect broke into a neighbor's home shortly before they saw Davey Blackburn leave the house, heading to the gym, and viewed it as "an opportunity," a law enforcement official said at a news conference Friday.

Blackburn said today that police "haven't given me a ton of details" and they've shared as much information with him as they have with the public, calling for help finding the suspect.

"Amanda didn’t have an enemy in the world. I can’t imagine any reason why. That’s why this has baffled us as much as anybody," he said.

"That’s why we’re trusting the investigators. They’ve been so good to us through this whole process, trying to keep us up to speed on what they have," he said.

The latest information that police have released is a still from surveillance footage that they believe shows the suspect on the morning of the crime.

The suspect has been described as a man with slim to medium build whose height could range from 5'4" to 5'9" and was seen wearing a two-tone hoodie sweatshirt on the day of the murder.

The most powerful form of relief for Amanda's family has been their faith, Blackburn said. The Blackburns moved from South Carolina to Indiana to establish the Resolute Church, and Blackburn said that their religious support has been a big factor in helping the family deal with their grief.

"What was so great about Amanda is that she was so selfless that she didn’t want her life to be put on display, ever, but she wanted Jesus to be put on display," he said. "We feel like that’s what happened at the celebration service, that Jesus was lifted up and people’s lives have been changed because of that."

Blackburn said one source of inspiration for him has been his wife's journal.

"I read Amanda’s journal entry just a few days before -- she journaled every day of her life -- just a few days before she was killed," he told ABC News. "She put something in there that just spoke volumes to us that we’re deriving strength from. She said, 'We don’t know what the future holds but we know who holds the future and that’s Jesus.' We’re drawing our strength from that and we know that Jesus holds the future and we can’t see it clearly but she sees it clearly now because she’s in Heaven with Jesus and we’ll see her soon."
