Pasadena resident Heber Enoc Diaz is accused in the killing of Chyong Jen Tsai, the Los Angeles County Sheriff's Department said in a statement.
According to authorities, the victim's white 2005 Lexus RX300 was found Thursday evening in the 900 block of Colorado Boulevard. Investigators located Diaz the following morning as he was leaving his home.
He was arrested without incident, booked for murder, and was being held without bail, the Sheriff's Department said.
Earlier in the investigation, sheriff's officials said they believed the killer ransacked Tsai's home. Her Lexus, with California license plates No. 5LOG473, was also stolen.
Tsai had been building a second unit on her property at the time of her death. A construction worker discovered her body on April 9.
