Police investigating the death of nurse Phuong Le have searched the home and office her married boss, who was the last person known to have talked to her, according to police.
Fairfield Police Lt. Darrin Moody would not go into details of Le's relationship with her boss, Thuc Nguyen, according to ABC News affiliate News 10, but Moody said it was "more than a work relationship."
ABC News talked briefly with Nguyen today.
"I'm cooperating with the police and the FBI right now. Been tiring. I can't comment on anything," Nguyen, 41, said.
"I'm very sad, and very upset," he said.
Le's brother Dinh told News 10, confirming it appeared to be romantic. Huong Le, another Le brother, told News 10 that Nguyen was married with children.
"That looks really strange to us because he's been a really good friend to our family," said Dinh, 31. "We didn't know they had a relationship like that. We didn't know at all."
Le's body was discovered about 30-yards off a road in a remote area of Napa County by a woman walking her dog, according to Moody.
"The Solano County coroner confirmed that the deceased female found in Napa was Phuong Le," Moody said Monday during a press conference.
Police have not identified any official suspects, however according to police they did search Nguyen's home and business, the Postal Express in Suisun City. Police have not revealed what items were taken during the search.
The family of the 25-year-old nurse from Northern California has been left lost, unsure what to do next after police positively identified her body Monday, Dinh Le told ABC News today.
"We don't know what to say now. We just, I don't know, we just pray," Dinh Le said.
Moody has withheld the cause of death other than to say Le's death has been deemed a homicide, according to Fairfield Public Information Officer Joel Orr.
"The cause of death is being withheld at this time because of the potential value it has in our ongoing criminal investigation," Moody said.
"I wouldn't classify it as well on our way to making an arrest. I will say we have information that we're moving forward on," the lieutenant said.
Le was reported missing by her family Sunday, April 25 after she had gone to a Barnes & Noble book stroe the night before, Dinh Le said. Her car was found in the parking lot of the bookstore, along with her personal items but there was no sign of her.

Dinh would not comment on his sister's relationship with Nguyen, saying he only hopes the police can locate her killer.
Le had recently passed a test to get her nursing license and was planning a big celebration with her family to coincide with her 25th birthday on April 30. Now her family is trying to recover from the confirmation of her death and arrange her funeral, Dinh Le said.
"I don't know what we're doing now, just waiting so we make plans for the funeral," her brother said.
