LAWRENCE, Kan. (AP) — Police in Lawrence have identified a man found dead near the Kansas River, but the cause and circumstances of the death are still unknown.

A volunteer with a river cleanup crew found the body just before 9 a.m. Saturday. Police issued a statement Monday identifying the man as 44-year-old Lawrence resident Troy A. Straub.

A preliminary examination found no signs of foul play. A report from the coroner’s office is pending.

The body was discovered near an area where homeless camps have been found and unattended deaths have been reported several times since at least 2008. Police said Saturday they did not know if the man was between homes at the time of his death.
