Segovia's family said he volunteered for a group that feeds the homeless and was active in helping to rescue animals.
Los Angeles Mayor Eric Garcetti was among the speakers during the funeral mass, along with Segovia's military friends.
"(He was) a man we shouldn't have to lionize in his passing, because in his living he was what we aspire to be. Not just in our service, but in our hearts," Garcetti said.
Segovia's body was buried at the Los Angeles National Cemetery in West Los Angeles.
"I thank God for giving me such a wonderful son and now my job is to keep his memory alive," Lopez said.
