Salomon/Juaca/Altagracia/Gloria are being accused of killing Emma. She got killed by LMdJ just like the Sebastian got killed. LMdJ even left her to die in the confession room. Gloria found her just like the way Altagracia found Sebastian on 3rd January. And now Alirio is playing Marcos' part by accusing Gloria of killing Emma.
But half the way he changes his mind and accused Salomon instead. (So he can get his hands on the del Toro fortune by marrying Gloria after Salomon got convicted ; dream on Alirio!!) He even call Emma's parents the Echenagucias to offer his theory that Salomon is the one who's responsible by the death of Emma.
*Kinda wonder, is Emma really is a Venezuelean cuz the name 'brandt / echenagucia ' doesn't sound latino. Also when Alirio made the call to Emma's parents to inform them about her death, he speaks in English.
