LATHROP – The young woman who died early Friday morning after she reportedly slipped and fell at the Mossdale Bridge in Lathrop was identified as 21-year-old Angela Marie Jacquez of Lathrop.

Close friends of the 2010 graduate of Sierra High School said Jacquez and three companions were hanging out at the historic railroad tracks during the pre-dawn hours when she tried to go up one side of the bridge, apparently to find a place to sit. But the morning dew may have made the metals slippery and she lost her footing. The friends reportedly did not see her actually fall but only realized what happened when they heard the sound of a “thud” and saw Jacquez lying on the railroad tracks. She had apparently hit her head on the train tracks.

San Joaquin County Sheriff’s spokesman Deputy Les Garcia said they received the 9-1-1 call about the incident at the bridge shortly after 5 o’clock in the morning.

“It was about a woman falling from the train trestle” at the Mossdale Bridge, he said.

“We’re getting all kinds of people’s take on it; it’s still being investigated,” Garcia said shortly after noon on Friday.

People close to the victim said she lived in Lathrop with her family and that she had recently signed up with the National Guard. After graduation, she enrolled at a nursing school in the Bay Area but later quit her studies and joined the National Guard.
