It’s been nearly a week since the tragic Thousand Oaks shooting that left 12 dead, but for those directly affected by the tragedy, the wounds are just as raw as ever.

The victims, most of whom were college-age, included Alaina Housley, the 18-year-old niece of Sister, Sister alum Tamera Mowry.

Mowry took her son Aden’s sixth birthday on Monday as an opportunity to pay further tribute to the late Alaina. Alongside a photo of Housley accepting flowers from her younger cousin, Tamera wrote, “Happy 6th birthday Aden! Alaina was excited to come to your birthday party. But as you said buddy, ‘She lives in your heart now.’ We love you.”

Mowry’s husband, Adam Housley, shared the same photo of Aden and Alaina, writing, “He was so excited to give you these flowers and as today as we celebrate his 6th birthday he says you are in his heart Alaina. We miss you so..but I know you are here and you are with him. Please be his guardian angel and Arian’s. Happy birthday Aden, as sad as we are, we are so blessed you have a heart like your cousin and we know you will carry her spirit for the rest of your life and make this world a better place. #thehousleys #adensbirrhday #alainasvoice#enough.”

Tamera first honored her niece’s memory late last week when she learned of her passing. “Alaina. My sweet, sweet Alaina,” she began. “My heart breaks. I’m still in disbelief. It’s not fair how you were taken and how soon you were taken from us. I was blessed to know you ever since you were 5. You stole my heart. I will miss our inside jokes, us serenading at the piano. Thank you for being patient with me learning how to braid your hair, and I will never forget our duet singing the national anthem at Napa’s soccer game. I love you. I love you. I love you. You are gonna make one gorgeous angel. My heart and prayers are with every victim of this tragedy.”

Tamera’s twin sister, Tia, shared her condolences as well.

We’re holding all the victims of this senseless tragedy in our thoughts, today and always.
