On the night of May 16, 2011, 52-year-old Sarina Marksberry was found lying in the roadway at 27th Drive and West Highland Avenue in Phoenix with grave injuries and taken to St. Joseph Hospital. She survived for six days but died on May 22, 2011. Investigators first treated the case as a hit-and-run because her injuries appeared consistent with being struck by a vehicle, but an autopsy later led the Phoenix Police Department to reclassify the death as a homicide.

The investigation has grown cold. Authorities expressed interest in speaking with her boyfriend at the time, Robert Reiss, though he was not publicly named as a suspect. No arrests have been announced and no suspects have been identified. Sarina is survived by a son and two grandchildren. A reward of $1,000 is being offered for information leading to an arrest and conviction.

Did anyone in Phoenix remember seeing Sarina on or around May 16, 2011, or have information about her last known movements?
