The Madison Police Department released new information Friday about a person of interest"" related to the killing of 31-year-old Joel Marino Jan. 28.
A police report described the person of interest as being a white male with a thin build.
Police did not initially release the person's race due to inconsistent reports from witnesses, according to MPD Public Information Officer Joel DeSpain.

Funeral services for Marino were held Saturday.
Police said Marino was found in an alley on South Park Street with stab wounds to his side. He was then transported to UW Hospital where he died.
