Police say a 44-year-old man was killed Monday night during a fight at the St. Vincent de Paul Society shelter in the city’s South of Market district.

Shelter workers told police that they heard yelling, then found the victim on the ground. Officers arrested 63-year-old Ricky Leon Scott about a block away.

The victim was taken to the hospital, where he was pronounced dead. His name has not been released.

The St. Vincent shelter is a drop-in center with 200 beds and 145 mats. It can accommodate 45 woman and 335 men nightly.

Shelter officials declined comment on the stabbing.
