Florida police said a Connecticut man who was biking from Maryland to Miami to propose to his girlfriend was fatally stabbed Monday night by a homeless man outside a McDonald's restaurant.

The Vero Beach News Journal reports that 28-year-old Kevin Adorno stopped at the fast-food spot and was talking to his girlfriend on a cellphone outside the restaurant when he was attacked. His girlfriend reportedly told police she did not hear the argument. She said she heard the phone drop and eventually police sirens.

Witnesses say Adorno stumbled into the restaurant. One person started administering aid while another called 911.

FoxCT.com reported that Adorno was stabbed several times in the chest and arm and collapsed near the bathrooms.

He was pronounced dead a short time later.

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