BATON ROUGE - Alton Sterling's aunt and the father of one of the officers killed in an ambush Sunday morning in Baton Rouge met at a growing memorial for the slain officers Monday night.

A photo taken by ABC News Correspondent Lana Zak shows Sandra Sterling and Hosea Jackson with their arms around one another at the B-Kwik gas station on Airline Highway.

Jackson is Montrell Jackson's father. Jackson was one of three officers shot and killed in the attack Sunday. In a press conference Monday, law enforcement indicated the gunman specifically targeted officers.

The death of Sterling's nephew, Alton Sterling, sparked demonstrations across the country. He was shot and killed by police earlier this month.

"It touches home because that's one block from where I live," Jackson said about the situation. "I feel so sorry and so hurt and I see how this unfolded and it's my son a couple of weeks after that. It's so sad. And it hurts."

" I was hurting for them and just wanted to let them know it's okay I know what they're going through and I want to hug them and let them know that I know, I understand and I'm so sorry," Sterling said. "I'm so sorry this happened."
