She worked at the operations center at the headquarters in downtown. She had been heading home when the Metrolink commuter train crashed head-on into a freight train last Friday, killing 25 people including Desha. Another 135 people were injured.
The procession started at LAPD Parker Center at 8:45 a.m. and headed along San Pedro to Temple, and continued from Temple to the cathedral, and the service started at 9:30 a.m.
Colleagues remembered Desha as a hardworking officer who loved her job.
As the investigation continues, authorities have released some of the 911 calls made by passengers moments after the deadly crash.
"I was on the Metorlink train. We had a collision with something. We have a whole bunch of people who are now bleeding and on the floor," one caller says.
"Do you know how many people are hurt?" the operators says.
"Well I can see about seven or eight people in the one car I'm in that are bleeding and on the floor," the caller says.
Another caller was told to move back because of a threat of an explosion from the freight train.
Immediately after the crash, dispatchers were flooded with calls, some from nearby residents, but mostly from passengers from the commuter train.
"The first car, looks like it's completely destroyed. I bet you're going to have a lot of fatalities there," said another caller to the dispatcher.
During another released 911 call, the dispatcher asked the caller who was screaming in the background.
"That's a person who was in a wheelchair who flew down the stairs from the top down to the bottom," the caller responded.
Authorities have now confirmed that the Metrolink train engineer Robert Sanchez was text messaging while on duty on the day of the crash. The 46-year-old engineer was killed in the collision.
The National Transportation Safety Board requested his phone records after two teenagers said they exchanged text messages with him shortly before the crash.
The NTSB is not saying how many messages were found in the records, but it was reported that one was received a minute before the crash.
NTSB investigators are also looking at every aspect of Sanchez's personal life history. He was first employed 12 years ago as an engineer at Union Pacific. Then he went Amtrak. Then, in 2005, he was hired by the company that provides engineers to Metrolink.
Investigators seek to find answers to why an experienced train engineer would ignore so many obvious warnings -- red signal lights, a rumble and shaking when the train rolled through a closed switch -- and then fail to brake when he saw the oncoming freight.
Investigators are also looking into whether Sanchez had any physical ailments at the time of the crash.
"The engineer reported to the conductor that he had a two-hour nap during his mid-day break," said Higgins. "The conductor was not aware of any physical ailments that the engineer had. The conductor had no information on medication that the engineer might be taking."
The Los Angeles County Coroner's office released a list of people killed in the crash.
