Investigators believe Jeffrey shot Riley before taking his own life, although his motive remains unclear.
Police believe the pair had been dead for “several days” before they were discovered, as reported by Need To Know.
Officers attended the property on the 2800 block of Mercer Street in Port Richmond, Philadelphia, Pennsylvania, US, and found the father and daughter with gunshot wounds.
Both were pronounced dead at the scene.
Riley’s death has sent shockwaves through the community, with loved ones remembering her for her “beautiful smile” and “infectious laughter”.
At the time of her death, Riley was studying in the School of Arts & Sciences at Holy Family University.
The university has paid tribute to the “bright” and “energetic” 21-year-old.
A spokesperson said: “We are deeply saddened by the tragic loss of Riley Costello, a student in the School of Arts & Sciences.
“Those who knew Riley will remember her bright, energetic presence on our campus and her kind soul, which left a lasting impression on all who crossed her path.
“She was a valued member of our Holy Family community, and her presence will be deeply missed.”
The university community is due to gather to remember Riley at the chapel at Nazareth Academy High School on 16 September.
Her family also paid a heartbreaking tribute to the much-loved student.
Riley’s obituary reads: “Riley was deeply loved by her mother, grandparents, aunts and uncles, cousins, extended family, and friends.
“She will be remembered for her humour, enthusiasm, and remarkable ability to make people feel special.
“Riley will be remembered for her beautiful smile, infectious laughter, adventurous spirit, and zest for life.
“Her life was a gift, and may we carry that gift forward by sharing the love and light she brought into the lives of others.”
Inspector D.F. Pace said investigators believe the shooting happened some time before the bodies were discovered.
He said: “Based on what we found, it appears the incident, the shooting itself, may have occurred several days ago.
“What might have motivated a father to turn the gun on his daughter and then on himself, it is still under investigation at this time.”
