Police say robbery appears to be the motive behind the killings at the Sacramento home.
Police described Lor as a parolee subject to high supervision who was released after serving time on gun possession charges.
Investigators say Lor has been identified as a gunman in a separate shooting of a 22-year-old man 18 hours earlier.
Police are investigating whether gang connections by members of the victim's family played a role in the attack.
