Robinson was born in Cleveland, Mississippi, into poverty, and was first arrested in 1918. He moved between Mississippi and Michigan. He also used the name James Coyner.
Between 1926 and 1934 women were killed in both states, stabbed or shot, and the bodies mutilated after death; he kept heads and other body parts. He was arrested on January 12, 1935.
This roster's status field reads that the sentence is unreported, and no accessible source records what he was convicted of, what he received, or what became of him. For a case of this description in 1935, involving a Black man arrested in Mississippi, the absence of any trial record is itself the most likely part of the story, and the entry says so rather than assuming a disposition.
The figure of six is what the accessible summaries carry. No victim is named and no killing is individually dated.
The entry is retained as a record of an arrest and an allegation. It should not be cited for six murders, and it belongs on the re-check list, though a 1935 Mississippi court record may not exist to be found.
