LANCASTER, TEXAS- A memorial service will be conducted Friday for six people killed by a family member who then turned the gun on himself.

The remembrance comes a day after a private burial on Thursday.

The shootings occurred on Christmas Day.

Authorities say 56-year-old Aziz Yazdanpanah (ah-ZEEZ' YAWZ'-dahn-pahn-aw), who had marital and financial problems, killed his estranged wife, their two teenage children, his wife's sister, his brother-in-law and his niece before turning the gun on himself at an apartment in the Dallas-Fort Worth suburb of Grapevine where his wife and children had been staying.

The brother of Yazdanpanah's wife, Ali Rahmaty (AH'-lee rah-MAH'-tee), a surgeon from London, says the shooter had been unemployed for more than a decade.
