Bahsid McLean Tanya Byrd

A man who dismembered his mother and scattered her body parts around the Bronx, took pictures of himself holding her severed head before disposing of her body, the NY Post reports.

Bahsid McLean, 23, confessed to the gruesome murder of his own mother, Tanya Byrd, who was the only caretaker of her 6-year-old Down syndrome son.

Police say the grinning psycho used a power saw to cut up his mother, then posed with parts of her body in grisly photos that he wanted as keepsakes. McLean and a friend, William Harris, 26, then stuffed Byrd’s body into several black garbage bags and a suitcase. They drove around the Bronx dumping Byrd’s remains like trash.

“He’s definitely sick,” a law enforcement source told the NY Post. Surveillance video from a hardware store shows McLean and his accomplice purchasing a brand new power saw and a refill blade with cash.

The saw and the blade were later found in a box in the home McLean shared with his mother and 6-year-old mentally disabled brother.

Friends described Byrd as a loving mother and caretaker to her Down syndrome son.

Police told the Post McLean killed his mother because she “wanted him to grow up and move out and be a man.”
