A day after four members of a Miami family were found shot to death in an apparent murder-suicide by the musician father, those who knew the Amadors say they're baffled about what led to their violent end.

But the MySpace and Facebook pages of the daughters of Pablo Josue Amador, 54, shed light on the inner turmoil his daughters were apparently feeling mere hours before the murders.

''Crying/hurting inside. Don't know how to deal. Not even gonna try attempting anymore,'' wrote Amador's oldest daughter Beula ''Bea'' Beatriz Amador, 20, on Facebook at 1 a.m. Wednesday, according to the Miami Herald.

She didn't go into detail in the posting written just five hours before her mother Maria Amador and younger sisters Priscila and Rosa were killed. Bea Amador, a student at the University of Miami, was not home and not among the victims of the massacre — nor was her 16-year-old brother, who escaped.

''I have gone through so much and yet I still try to stand tall, because this whole world is coming down on me, and me blocking it hurts more and more,'' Priscila, 14, wrote on MySpace."That's why I don't care anymore.''

It was not immediately clear what either daughter was referring to in their posts on MySpace and Facebook.

Those who knew Pablo Amador, a music teacher and former opera tenor, described him as a "regular dad" who made music with his children and taught kids to play piano. They are confounded over what led him to snap.

"It confuses me," said 48-year-old Thelma Vallecillo, whose 13-year-old daughter Rosa took piano lessons at the house. "I don't understand."

Investigators carried out the four bodies of Pablo, his 47-year-old wife and two young girls on Wednesday, found inside their gray-trimmed, white ranch house.

The son who escaped the shootings uninjured called 911 at 5:58 a.m. as he fled the home, police said. Authorities have not said where he is now.

Amador's two slain daughters and college-aged daughter all excelled at piano and performed together at church and home as Los Galileos, said Sarait Betancourt, a 44-year-old school bus driver who lives near the family.

Amador said on his Web site that he produced 13 CDs of his children performing.

A biography of Amador posted on a Web site advertising his piano classes says he began studying music in Havana and later earned a degree in the U.S.

The U.S. Copyright Office lists 36 compositions by him and a set of photographs. The songs he wrote, many in Spanish, included titles such as "Beautiful Boy" and "Rose of Love," as well as numerous religious selections.

His wife was the education director at the University of Miami's Project to Cure Paralysis.

Neighbor Betancourt said Amador was a Cuban immigrant who has been giving her two sons, ages 9 and 10, piano lessons at his home once a week since 2006.

"He was a marvelous person and a tremendous professor," she said. "People would enter the house, and you just breathed peace."

Music could always be heard coming from the house and children often played in its in-ground pool, remembered Gregorio Montesino, who lives nearby. He said Amador always waved to greet him.

Next-door neighbor Christina Ruiz, a 23-year-old social work student, described Amador as a "regular dad" who helped her grandmother jump-start her car several times but who was known to complain when he was bothered by noise or work being done on her house.

Amador sang tenor with the Greater Miami Opera chorus and was a soloist at Kendall United Methodist Church, he said on his Web site. Officials at both weren't able to confirm that information.

Those in the community said that Amador worked at a music store, in addition to giving lessons.

His wife had nursing degrees; as director of education at the Project to Cure Paralysis, she taught about spinal cord injuries and answered calls from patients looking for the right doctor.
