A police firearms examiner testified Tuesday a specific type of handgun was probably used to murder an El Camino High School soccer player shot to death on the front lawn of his home in Canoga Park in 2012. 

LAPD criminalist William Moore told jurors in Van Nuys he examined four expended cartridge cases and two fired bullets connected to the murder and opined the shots were fired from a .40 caliber pistol, most likely a compact and expensive model made by Sig Arms.

One of the bullets was found outside the home of 17-year-old Francisco Rodriguez. The other was dug from his body during the autopsy at the L.A. County Coroner's office.

"These two bullets were fired through the barrel of the same firearm," Moore told jurors, explaining marks left on the bullets were examined under a microscope to make the match.

Moore's testimony came on the second day of the trial of 24-year-old Jason A. Schumann, who prosecutors say killed Rodriguez out of jealousy.

Schumann and his girlfriend Elizabeth Ibarra were arrested about a week after the killing on January 11, 2012.

On Monday one of Ibarra's cousins testified she introduced Rodriguez to Ibarra while Schumann was serving time in L.A. County jail and the two became friendly.

Schumann, police said, became enraged when he was released from jail in late 2011 and learned Ibarra and Rodriguez had been communicating.

LAPD detectives said they suspected Schumann forced Ibarra to lure Rodriguez from his home on the evening of the shooting in order to confront the teenager.

Rodriguez, known to friends and family as, "Pancho" or "Panchito," had returned from a soccer team trip to Hawaii the day before he was killed.

El Camino classmate Osvaldo Martinez testified he and Rodriguez had eaten Subway sandwiches for lunch on the day of the murder, and said had driven Rodriguez home from school less than an hour before the shooting.
