Manuel Pinon, 48, was the oldest of four brothers who grew up in San Jose. He leaves behind his wife Melina, four children in their 20s, his parents and grandparents.
Pinon was a heavy equipment operator at the Lehigh Cement Plant where he was killed.
Melina never worked outside the home during their 27 year marriage. She now faces possible foreclosure and a cancer diagnosis without him.
"She has an inoperable tumor that has to be shrunk," Manuel's aunt Luz Brown said. "How will she make ends meet?"
Brown says Manuel had worked for 15 years at the Lehigh Cement Plant. The company is covering funeral costs but she's not sure about anything else.
Brown is a Santa Clara County sheriff's deputy, and would eventually like to ask what Lehigh knew in advance about the shooter, Lehigh employee Shareef Allman.
"If this gentleman was problematic and it was ongoing issue, at what point was it going to be addressed? Obviously we'll never know now. It took three deaths to realize this man had issues," Brown said.
For now Brown is focusing on the funeral, planned for Wednesday, where Manuel will be remembered as a man who appreciated what he had, who worked hard during the week and cherished his weekends.
"A faithful 49er until the end, the 49ers and Carlos Santana -- what he lived for on the weekends, great guy," Brown said.
The non-profit Mothers Against Murder is helping Manuel's family get through the devastating time and has set up a memorial fund.
"There is just so much hurt, a life was taken, but that life that was a part of so many other lives," Executive Director Margaret Petros said.
Company officials at the Lehigh Cement Plant say their workers returned Monday to begin bringing the plant's operations back online.
