VAN NUYS, Calif. (KTLA) -- The two suspects in the shooting death of a 17-year-old star high school soccer player are facing new charges in an unrelated armed robbery, the District Attorney's office said.

24-year-old Jason Alejandro Schumann and 19-year-old Elizabeth Ibarra have been charged with one count each of second-degree robbery, Deputy District Attorney Beth Silverman said.

They are accused of robbing a man of his cell phone behind a San Fernando Valley Market on Dec. 29, 2011.

Schumann is charged with personal use of a handgun.

Both Schumann and Ibarra are scheduled to be arraigned in Van Nuys Superior Court Wednesday morning.

Schumann will also be arraigned on murder charges in the fatal shooting of Francisco "Pancho" Rodriguez.

He is being held on $2 million bail in connection with that case.

Rodriguez was shot and killed the evening of January 11 outside his home in the 6900 block of Cozycroft Avenue in Winnetka.

Ibarra was also arrested by LAPD. She is a suspect in the case, but no charges have been filed against her.

Police say Ibarra was recently released from L.A. County jail after serving part of a six-month sentence for forgery.

She had been in custody since her arrest Oct. 31, but was released on Jan. 4, a week before the fatal shooting.

Ibarra also has convictions for identity theft and assault on a police officer.

She is being held in custody for violating her probation.

Investigators believe a romantic link between Rodriguez and Ibarra was a possible motive for the shooting.

Ibarra's Facebook page lists Rodriguez as a friend. A photo of Schumann, Ibarra's boyfriend, is also posted on her Facebook page.

Rodriguez apparently wrote comments on Ibarra's Facebook page that made Schumann jealous.

Police say Rodriguez was lured outside of his home by a girl with red hair who knocked on his door, believed to have been Ibarra.

Police say Ibarra is not a natural redhead, and authorities believe she dyed her hair to throw off witnesses and authorities.

Rodriguez told his family that he was stepping outside, and he was almost immediately shot by a man in a waiting SUV.
