The deranged man who opened fire in a Tennessee church last month, had a note in his car calling white supremacist Dylann Roof “less than nothing,” according to a new report.

Police say Emanuel Kidega Samson, 25, killed a woman while she was running away and injured seven others in the shooting at Burnette Chapel Church of Christ on Sept. 24., though the investigation into his motive in ongoing, Nashville Detective Steve Jolley testified Monday, according to the Tennessean.

Jolley said a note reading, “Dylann Roof was less than nothing,” was found in the alleged shooter’s car, referencing the 2015 Charleston shooting where Roof killed nine black parishioners at the historic Emanuel AME Church.

The note didn’t make it clear whether Samson, who is black, intended to retaliate against the Charleston attack, Jolley said.

The Sudanese immigrant also, “made some comments about visions and voices,” including a vision of the very church he allegedly shot up, Jolley testified.

Samson is being charged with criminal homicide and the feds have an open civil rights investigation into the case that will seek to determine the motive.
