Nick Carter remembers his 'baby brother' Aaron Carter

NEW YORK (AP) — The day after 34-year-old singer Aaron Carter was found dead at his home in Southern California, Nick Carter, the Backstreet Boys member, remembered his younger brother

In a posting Sunday on Instagram with photos of the two through the years, Nick Carter said his heart was broken after the death of the youngest of five Carter siblings, whom he called his “baby brother.”

“My heart has been broken today,” wrote Carter. “Even though my brother and I have had a complicated relationship, my love for him has never ever faded. I have always held onto the hope that he would somehow, someday want to walk a healthy path and eventually find the help that he so desperately needed.”

Deputies responded around 11 a.m. Saturday following reports of a medical emergency at Carter's home in Lancaster, California. Authorities said a house sitter found a man in the bathtub in the home and resuscitation efforts were unsuccessful.
