WASHINGTON — A funeral service was held Wednesday for the 3-year-old girl who was accidentally shot and killed by her brother last week.

Dalis Cox was shot in an apartment along 46th Place, near Benning Road in Southeast D.C., according to police.

Investigators say Dalis’ 7-year-old brother was playing with a gun when it fired. Police say the gun was illegal. They don’t know how the 7-year-old got to it.

The funeral service took place at New Smyrna Missionary Baptist Church in Northeast.

“She’s going to be truly missed,” said Angela Jordon, a cousin of Dalis’ father, Timothy. The girl was “very bubbly,” Jordon said, and “very, very happy.”

Dalis Cox is survived by seven brothers and sisters, her mother, father and grandparents.

She was to be buried at Mount Comfort Cemetery in Alexandria, Virginia.
