An Ohio-based rapper said he received an email from Gavin Long less than an hour before the gunman killed three law enforcement officers in Baton Rouge, Louisiana.
Yarima Karama said in a video posted online that the email included images of a three-page, handwritten letter. The subject line of the email was "manifesto."
Police say Long stalked Baton Rouge officers on Sunday before shooting six of them in an ambush, killing three — Baton Rouge police Officers Montrell Jackson and Matthew Gerald and East Baton Rouge sheriff's Deputy Brad Garafola — and wounding three others.
CNN is working to confirm the authenticity of the email with law enforcement. Louisiana State Police said it was investigating the letter and noted other writings were recovered in Baton Rouge but would not confirm whether the shooter authored them.
Karama told CNN that he received the letter at 9:04 a.m. ET.
Authorities said they first received reports of the shooting about 40 minutes later.
