Miami-Dade County police found four bodies, victims of a murder-suicide, inside a south Miami-Dade home on Wednesday morning.

The dead were identified as former tenor and piano teacher Pablo Josue Amador, 54; his wife, Maria, 47; and daughters Rosa and Priscila age 13 and 14. One son, Javier, 16, survived by running out of the house. Another daughter, Beula Beatriz, 20, a student at the University of Miami, also survived.

The teenage son called police from a cordless phone as he ran away from the house, police spokesman Detective Alvaro Zabaleta said, according to Miamiherald.com.

Police said the shooter was the father, who previously sang with the Greater Miami Opera chorus, now the Florida Grand Opera, and sang at Kendall United Methodist Church. The reason for the killing remains unknown.
