Peat, 39, died from stab wounds and asphyxiation up to eight days before his body was discovered. Authorities were alerted by the strong smell coming from his house.
Peat was found with his hands and feet bound and with traces of masking tape on his face. None of the locks had been forced, suggesting the culprit may have been someone he knew.
Peat sold his home in downtown Guadalajara and began renting the house in Colonia Moderna around six months ago. In the last month he had used the money from the sale to buy a blue Mazda 3 and several new electrical appliances, all of which were stolen.
An accomplished interior designer, Peat received formal recognition of his work from the city council in February. He won second place in the Annual Award for Conservation and Restoration and received 30,000 pesos in prize money from Aristoteles Sandoval, then mayor of Guadalajara.
