Roberto Eduardo Wolfenson (71) was murdered in his home in La Delfina, in Derqui. Autopsy determined that he was murdered on Friday, February 23, but witnesses question the expertise.

On Thursday Wolfenson went for a walk as usual but on Friday he did not attend his group or go out to do his 6,000 daily steps. The body appeared in a guest room, without the sheets (which were in the washing machine unwashed) and without signs of a fight or blood stains.
