Bobbi Kristina Brown Buried Next to Whitney Houston In New Jersey

The aspiring actress died last month at the age of 22.

The burial comes two days after Brown was memorialized at a funeral in Alpharetta, Georgia.

“Krissy was and is an angel. I am completely numb at this time," he told ABC News the day after her death. "My family must find a way to live with her in spirit and honor her memory. Our loss is unimaginable. We thank everyone for the prayers for Krissy and our family as we mourn my baby girl."

Authorities are investigating the circumstances surrounding Brown's death, according to a representative for the Fulton County district attorney's office. The Fulton County medical examiner said that an initial portion of the autopsy did not show an obvious underlying cause of death, and additional laboratory tests are being conducted.
