A New Jersey man has been sentenced to eight years in prison for stabbing to death a retired Catholic school teacher during a dispute over feeding pigeons at a local park.

Charles Lowy, 69, stabbed 77-year-old Anthony Bello in April 2018, NJ.com reported. Lowy was convicted of reckless manslaughter this past July.

Lowy’s defense attorney reportedly said it was the 69-year-old’s routine of feeding the birds by scattering food in a circle around him that set off the argument between the two men in Pershing Field Park in Jersey City.
