INDIANAPOLIS — In a tragic new development, police told WTHR Friday that the pregnant daughter-in-law of a North Carolina pastor, who was murdered in Indiana, was also sexually assaulted.

Police are still following several leads in the murder of 28-year-old Amanda Blackburn, who died after being shot in the head by a gunman.

One of the people who was interrogated by police on Thursday, Jalen Watson, 21, was taken into custody for a parole violation.

“Our detectives believe this was a robbery likely to have gone foul,” said Indianapolis Metro Police Sgt. Kendale Adams.

According to WTHR, some of Blackburn’s bank cards were used at a gas station after the home invasion.

Crime scene investigators have processed the home for evidence on two occasions, looking for anything that could lead them to the killer.

“To the individual who committed this crime, you are not as good as you think you are…got away with it, but you left something behind and we will find you, we are coming to get you,” Asst. Commander Eric Hench said at a news conference last week.

Several sources close to the investigation told WTHR that DNA evidence may play a major role in identifying Blackburn’s killer.

The victim and her husband have a 1-year-old son. The victim’s father-in-law is the pastor of NEXT Church in Brevard, N.C., according to WLOS.

Amanda Blackburn’s husband, Davey Blackburn, is a pastor at Resonate Church in Indianapolis. The church posted a note to Facebook last Wednesday about the incident.

“It’s impossible to communicate all the emotions my heart has been forced to process. My wife was such a beautiful, gracious, loving woman of God,” Davey Blackburn’s statement read, in part. “I have not only lost my ministry partner and support but also my very best friend. There is no way to prepare yourself for circumstances like these.”
