The president of a synagogue in the US city of Detroit, Samantha Woll, has been found stabbed to death in a park not far from her home.
Police said they responded to a call in the Lafayette Park area on Saturday and found the victim unresponsive, but they believe she was killed at home.
They searched the area with dogs but there is no information yet about who carried out the killing, or why.
Officials paid tribute to Ms Woll as “one of Detroit’s great young leaders”.
Michigan State Attorney General Dana Nessel wrote on X that she was “shocked and horrified to learn of Sam’s brutal murder”, while state governor Gretchen Whitmer described the murder as a “vicious crime”.
“She was a source of light, a beacon in her community who worked hard to make Michigan a better place,” she said in a statement.
Police had promised to provide more information but warned against drawing conclusions before the facts were established.
