SAN CLEMENTE There was no note and authorities said there is still no explanation as to what happened inside a home in Sea Point Estates, where a family of five was found dead three weeks ago.

Investigators have not ruled out a possible suicide pact or murder suicide. What they do know is that sometime around the first week of May, Manas Ucar, 58, and his wife, Margrit Ucar, 48, were both shot in a first-story bedroom in their home. Two guns were found on the floor near to the couple, although investigators won’t say if both were fired, and if so, by whom.

Their twin daughters, Margo and Grace, were found lying in a bed in the room. Margrit’s mother was found dead in a chaise in the room. They had no bullet wounds.

The bodies of the family were not found until about three weeks after their death, when family members grew concerned. On the day of Margrit’s birthday, they decided to break a window and look inside the home, making the gruesome discovery.

On Monday night, investigators with the Orange County Sheriff’s Department held a meeting with residents of the gated community to share one important fact they say they are sure about – the only people involved in this case were those who were found inside the home.

“Nobody came in and left,” said Investigator Dan Salcedo of the Orange County Sheriff’s Department. “There is no cause for fear or alarm.”

Investigators from the sheriff’s homicide division were called to the gated community when family members found the five bodies inside the home on May 25. There was no sign pointing to a homicide, but investigators were called because of the number of bodies found inside, Salcedo said.

“It’s very rare that you get more than one suicide, but five is extremely rare,” Salcedo said.

But authorities have yet to find an explanation, he said. Investigators have interviewed relatives and friends of the family, but they seemed to be as bewildered as investigators, he said.

Friends described the family as religious, loving and overprotective at times. Manas Ucar, a former professor at Syracuse University, was a consulting engineer. The two daughters had finished their courses at UC San Diego in January.

Marital, financial or personal problems are common factors in suicides, but nothing seems to explain what may have caused this to happen, Salcedo said. Authorities will be interviewing family members from out of state this week to see if that may provide a clue.

Toxicology results on the four bodies are also expected in about a week.

Investigators were looking as to why all family members were wearing black when they were found, but family members said it was common for the family to dress in black. The two girls and their mother also dressed alike often, Salcedo said.

“The family may never find out why,” Salcedo said. “I wish I had an answer, especially for the family.”
