Dayton mass shooter Connor Betts had a pocketful of receipts on him during his massacre — which were reportedly for mental health services that he had received.

The receipts were for $50 payments that Betts, 24, allegedly made for counseling and other services back in April and June, according to the Dayton Daily News.

They were reportedly covered in blood and made out on three separate dates. Autopsy photos examined by the Daily News listed two of the dates — April 5 and June 10 — but the third could not be read.

Police officials have previously said that Betts retrieved psychiatric treatment, but it was unclear when and for what. Local media outlets have spoken to multiple people close to him who said he had a number of mental illnesses — including depression and possible bipolar disorder.

Autopsy results released Thursday, along with the photos that listed Betts’ belongings, showed that he had cocaine, Xanax and alcohol in his system during his Aug. 4 shooting rampage.

The young man is accused of killing nine people — including his sister — outside a bar area in Dayton. He was fatally shot by police.
