? Police are investigating the stabbing of a man who stumbled to a Bridgeport neighbor?s doorstep seeking help before dying Saturday night.

Raul Mendez, whose home is on Sanford Avenue, says he went to his door to see what his dogs were barking at around midnight. Mendez found 29-year-old Jose Osario with several stab wounds to the chest. Osario was taken to the hospital where he later died.

Police have not made any arrests, but are investigating the incident and neighborhood. This is Bridgeport?s fifth homicide in the past two weeks.
