FRISCO, 

Texas (AP) — 

           North Texas woman charged with killing her 10-year-old son cried as she joined dozens of mourners at a candlelight vigil for the boy.

          Pallavi Dhawan attended Wednesday night's gathering outside her family's home in Frisco, 25 miles north of Dallas. Dharwan was charged with murder after police officers making a welfare check at the house Jan. 29 found the body of her son, Arnav, in an empty bathtub. The body was wrapped in a cloth up to the neck, and there were empty plastic bags in the tub next to him.

           Toxicology results are pending.

           Dhawan remains free on $50,000 bail. Her attorney, David Finn, said she has denied killing the boy.

Arvan was a special-needs child, born with a brain cyst and microcephaly, a condition characterized by an abnormally small head, Finn has said.

The mother and her husband, Sumeet Dhawan, both shed tears during the vigil.

           "When you lose a child, you lose a child. You really don't have time for those things," Pallavi Dhawan said, responding to the allegations against her. "Forget his ailments and everything, you know. Other than that he was a boy, a little kid."

             One mourner sang "Amazing Grace." Some of Arnav's friends also attended. Cards and toys, including a stuffed bear, were left at the yard.
