A MAN who was biking from Maryland to Miami to propose to his girlfriend was fatally stabbed by a homeless man outside a McDonald’s restaurant, police say.

The Vero Beach News Journal reports that 28-year-old Connecticut man Kevin Adorno stopped at the restaurant on Monday night and was talking to his girlfriend on a mobile phone when he was attacked.

Witnesses say Adorno stumbled into the restaurant. One person started administering aid while another called emergency 911. He was pronounced dead a short time later.

Officers arrested 59-year-old homeless man Rene Herrera Cruz at a Burger King across the street. He is charged with first-degree murder.

Mr Cruz told officers he thought Adorno was directing people by cellphone to attack him.

Police Chief David Currey says the trip was a “bucket list” item for Adorno.
