According to the reports, the 30-year-old songtress was not at home and construction workers found him lying on a mat in the garage.
Police found Zachary's whereabouts after he left behind a notepad with disturbing messages professing his love for the "Blue Jeans" hitmaker, reported TMZ.
In one of the messages he claimed he was "engaged to heaven on Earth with Lana Del Rey."
Zachary was held by police in December told them he had become obsessed with Rey while under the influence of hallucinogens.
The court has ordered Zachary with five years on probation and a year in a residential program. He has been asked to stay clear of the singer for the next 10 years.
