Amanda Blackburn, 28, was 12 weeks' pregnant with her second child, according to a local report.  She and her husband, Davey Blackburn, already had one young son and had moved from South Carolina in 2012 to start the Resonate Church, according to the report.

Blackburn was home alone with her son when she was shot in the head at her home Tuesday morning, police said. Her husband had been at the gym and returned home to find her shot, police said. Police said there was a struggle as Blackburn defended herself before being shot.

Suspect seen on video

ho investigators believe broke into an Indianapolis home and fatally shot a pastor's pregnant wife after burglarizing a neighbor's home, police said Friday.

Detectives are seeking the public's help in identifying the hoodie-wearing suspect in Amanda Blackburn's killing. The suspect is a black male with a medium to light-brown complexion, slim to medium build and between 5-foot-4 and 5-foot-9, City police Capt. Craig Converse said during a news conference. His age isn't known.

"We know who killed her. At least we have a picture of him, but we don't know the name," he said, adding that the suspect was seen near the Blackburn's home.

Blackburn, 28, was shot in the head during the attack Tuesday morning and died the next day. She was 13 weeks pregnant, and the child did not survive, family spokeswoman Suzanne Swift said. The Blackburns also have a 15-month-old son, who Converse said was upstairs in a crib at the time of the attack.

Investigators believe the suspect, whom neighbors also reported seeing walking in the area, may have seen Blackburn's husband, Davey, leave home about 6:10 a.m. Tuesday to go to a gym. That was shortly after the suspect allegedly burglarized a nearby house.

At least three security cameras at other homes — including one inside the burglarized home — captured images of the suspect in what is a normally quiet neighborhood on the city's northwest side near the Indianapolis Museum of Art.

Maj. Eric Hench said police planned to release an image of the suspect.

A neighbor heard possible gunshots between 6:45 a.m. and 6:55 a.m. Tuesday and home security video shows a dark SUV speeding from the neighborhood, Hench said. Because "sizeable" televisions and a laptop were taken from the burglarized house, he said investigators believe those items "were likely loaded into a vehicle," suggesting that others might have been involved.

But, Hench said, it's unclear if the SUV seen in video footage is connected to the crimes.

Hench also said the suspect had left evidence behind and issued a statement directed at that person.

"You're not as good as you think you are. You left behind evidence, we have found it and we will find you and we will not stop until we get you," he said.
