April Kauffman's murder remains unsolved.
She was shot repeatedly inside her home in Linwood back in May of 2012.
Police questioned her husband James, a local doctor, and several others. So far, police have made no arrests.
At a candlelight vigil behind Mainland High School on Saturday night, loved ones vowed not to let Kauffman be forgotten.
"April is a special person to me, I've known her 30 years. We raised our daughters together, did a lot of charity work together. I miss her," said a friend of Kauffman at a vigil Saturday.
Kaufman was also a well-known advocate for veterans' issues. The gathering also served as a fundraiser for one of her favorite charities.
