One of four panhandlers charged in connection with the stabbing death of a St. Catharines man has pleaded guilty.

Faith Watts pleaded guilty Monday to assaulting a police officer and obstructing justice after being involved in a brutal attack on a tourist walking around the Queen Street West neighbourhood this past summer.

Ross Hammond and his friend were surrounded by a group of panhandlers asking for money around 12:30 a.m. on August 9. The two men refused to give them cash and an argument ensued.

Hammond was stabbed several times in the chest and died in hospital a few days later.

Watts and three others were charged. Only one of the panhandlers is a Canadian citizen. The other three, including Watts, are all from the United States.

Watts, a 22-year-old from California, admitted head-butting a police officer while being arrested and impeding paramedics trying to wheel Hammond into a waiting ambulance. She also pleaded guilty to giving police a false name, Sarah McDermit, when arrested.

She will serve two months in jail in addition to the two months she has already served.
