Ex-partner of confessed killer in Mariana Sepúlveda case details post-stroke personality change

The ex-partner of the neighbor who confessed to killing Mariana Sepúlveda has provided testimony describing his behavioral changes after a stroke, as part of ongoing proceedings by the Public Ministry and Carabineros. The case is notable because the statute of limitations for the crime expired last Friday, complicating potential prosecution. The testimony may influence public perception and legal arguments regarding criminal responsibility, though its evidentiary weight remains uncertain.
