In those documents, police reveal they connected 19-year-old Robert Davis to the October 2 murder of 39-year-old Josh Kruger through texts and voicemails.
One of those voicemails was recorded three minutes before Kruger was fatally shot inside his Point Breeze home.

Kruger is heard telling someone at his door to "get out of here" and that "I'm tired of you being mean to me."
Police say the phone number that left the voicemail matches a number that belongs to Davis.
Kruger was a freelance journalist and former city employee. He was shot seven times in the chest and abdomen.
Sources told 6abc that drugs were found in Kruger's home.
Kruger was openly queer, according to District Attorney Larry Krasner, and often wrote about LGBTQ+ topics, as well as drug abuse and homelessness.
