At 12:55 a.m. on the morning of April 11, 2012, records show that Javier Bolden received a phone call that lasted for about six and half minutes. Later that morning, two University of Southern California students were shot dead in their BMW in South L.A.
What connections do these two events have?
That seems to be the point the prosecutor is trying to make on the third day of Javier Bolden’s trial, who is facing charges of first degree murder, attempted murder, and assault with a firearm.
Bolden is accused of murdering two 23-year-old USC graduate students, Ming Qu and Ying Wu, while they sat in a parked car in a neighborhood near campus.
Though only halfway through today’s trial, Deputy District Attorney Dan Akemo has brought forward multiple witnesses to testify about phone records that show Bolden receiving a call.
Luisa Aznarez, an AT&T retail sales manager, explains cell phone coding.
Stefano Bowe, the third witness called to the stand, works at Track Phone. He brought with him the company records that linked Bolden to a specific phone number that received a call early on April 11.
Luisa Aznaraez, an AT&T retail sales manager for the the past eight years, and Ronald Witt, a senior specialist in the law enforcement group for T-Mobile, separately took the stand to explain that cell phones each have a unique code. Once a number is set up with a specific person, each call from that phone is recorded. The records show a location based off the closest cellular tower.
L.A. Detective Sean Hansen explains the work behind linking cell phone calls to crimes.
Los Angeles Detective Sean Hansen, a member of the the FBI Cellular Analysis Survey Team, took the stand right before a lunch break was called. He works with 32 federal agents across the United States to use cellular information.
Before the judge called for a break in the trial, Hansen explained that cell phone towers are broken into sectors. CAST uses information from the cell phone companies—records, tower lists —and a specific software to measure the size of the cell site sector. This allows the team to pinpoint the location of a person during a particular phone call.
When the trial returns, Hansen will retake the stand.
