WINDSOR LOCKS, Conn. (AP) – Police were still searching Thursday for the families of two victims in Tuesday night’s double murder and suicide at a local nail salon.

The owner of Queen’s Nails, 22-year-old Anh Qui Bui, of Springfield, Mass., and two men were killed in the shooting, police said.

Investigators plan to execute a search warrant this week on two cars towed from the scene as evidence, Capt. Chester DeGray said. Those cars had New Hampshire plates, police said.

Tracing the plates on the cars has not helped police locate family members, DeGray said.

Investigators will not release the names of the victims until their families are notified, DeGray said.

“We’re not sure where these people are,” DeGray said. “There very well may be relatives in this country, but there may not.”

All three victims are Vietnamese, police said.

“We do have ID’s, but want to be sure those ID’s are correct,” DeGray said.
