Riley Costello Obituary: Philadelphia Neuroscience Student Remembered at 21

Riley Aine Costello, a 21-year-old Philadelphia resident and neuroscience student at Holy Family University, died on August 15, 2026. Her family and friends are remembering a young woman whose humor, adventurous spirit and enthusiasm made her a memorable presence in their lives.

Born February 6, 2005, in Philadelphia, Riley was the beloved daughter of Kelly Elizabeth O’Drain. Her official obituary, published by Lambie Funeral Home, describes a life filled with friendships, family connections and a willingness to embrace new experiences.

Her passing came while she was pursuing her university education and looking toward the opportunities ahead of her.

From Little Flower to Holy Family University

Riley attended Mother of Divine Grace through eighth grade before graduating from Little Flower High School.

She later enrolled at Holy Family University, where she was studying neuroscience. Her obituary describes her as enjoying her college years, surrounded by friends and the experiences that came with university life.

Those educational milestones form an important part of her story. They reflect a young woman who had moved from her Philadelphia school community into a new stage of learning and personal development.

Although her time at university was cut short, the friendships and experiences she built there remain part of the memories shared by those who knew her.

A Personality Friends Will Remember

Riley’s family remembered her as beautiful, funny, outgoing, spontaneous and a little mischievous.

She enjoyed dancing, laughing, spending time with friends and family, and making memories with the people she loved. Her obituary also emphasizes her ability to make others feel special, a quality that appears repeatedly in the tributes left by friends.

One friend recalled that Riley could make people smile even when she was having a difficult day herself. Another remembered her as someone who could always be counted on to be there when a friend needed support.

These personal accounts offer a picture of Riley beyond her age and academic achievements. They describe someone who brought energy to social gatherings and whose friendships were built through both everyday moments and shared adventures.

Family and Loved Ones Mourn Riley

Riley was deeply loved by her mother, grandparents, aunts, uncles, cousins, extended family and friends.

Her family’s obituary encourages those remembering her to carry forward the kindness, laughter and spontaneity she brought into their lives. It invites loved ones to make someone laugh, do something unexpected and embrace the kinds of experiences Riley enjoyed.

The message reflects the way her family wishes her to be remembered: not only through the sadness of her passing, but through the joy and affection she shared with others.

For her friends, memories of dancing, laughter and time spent together will remain an important part of her legacy.
