2The couple who allegedly murdered a pastor and took a series of selfies in his car
The pastor was shot to death the day after Halloween 2014. His body was found floating in a pond, and his wallet and car were missing. The couple was arrested a few days later in Greenville, Mississippi after being pulled over in the stolen car.
The couple is on trial as of this writing — Williams insists the whole incident centered around an arrangement for prostitution with the pastor. However, prosecutors believe the couple just wanted to steal the pastor's car. (Source)
3A grieving widow kills her father-in-law and posts a selfie with his corpse to Instagram
Amanda blamed Charles Taylor, 59, for her husband's addiction issues. On March 27, and on their joint birthday in 2015, Amanda went to Rex's graveside and tried to take her life. She survived and checked herself into the hospital. Despite her protests and objection from her mother, Amanda was released. A few days later, she visited Charles and stabbed her former father-in-law as he sat on the sofa. She made it happen at exactly 3.27 pm to symbolize the birthday she'd shared with Rex — 3/27.
After the killing, she posted another status on Instagram alongside a picture of a news report alerting members of the public that she was on the run. She had also taken a selfie at the scene with the bloody knife and the body of Charles behind her.
Amanda was arrested in North Carolina and has since been found guilty of murder in the first degree. She currently awaits sentencing. (Source)
