20-year-old Bryan Bridgeford and 20-year-old Jose German were arrested early Tuesday morning, along with a 17-year-old whose identity is not being released. Thursday, a 16-year-old was also taken into custody.
The four suspects are accused of shooting 16-year-old /*Leonel Medina*/ and 21-year-old /*Juan Avalos*/ while the two were listening to music in Medina's garage last week.
Detectives also believe they now know the motive for the execution style shooting.
Merced County /*Sheriff Mark Pazin*/ said, "The two victims and the suspects had been in a verbal feud in the weeks leading up to this murder. And there are some gang overtones."
Detectives have also recovered a weapon they believe was used in the murders.
