Twins Found Dead After Mother Died By Suicide Are Remembered as 'the Sweetest Kids'

Ava was the "talkative" one, and Ahmad was the shy one, their father Xavier Jackson said in a GoFundMe post

A father is mourning the death of his 5-year-old twins after they were allegedly killed by their mother shortly before she jumped to her death in Florida.

Xavier Jackson, who identified himself as the father of Ahmad and Ava Jackson in a GoFundMe created on Saturday, said that his children were “the sweetest kids” and remembered his daughter as the “talkative” one and his son as the “quiet observer.”

“The few years GOD allowed them here was wonderful," Xavier said the fundraiser. "It’s so unreal that I have to plain (sic) a funeral for my twin babies.”

“I feel an extreme amount guilt as if I failed them,” Xavier wrote, adding that he is now left wondering if he could have done anything “differently to prevent this.”

Authorities discovered the children's bodies in a Sanford, Fla., home on Friday after their mother, Catorreia Hutto was found in a nearby river, PEOPLE previously reported.

According to Sheriff Dennis Lemma, early Friday morning, deputies with the department responded to a call from an eyewitness claiming a motorist had stopped their vehicle on the crest  of a bridge.

The caller told officials that a woman seemed to slide out of the passenger window of her vehicle and jump into the St. Johns River in “what appeared to be an attempt at a suicide,” Lemma said.

Once deputies arrived at the scene, they saw a woman floating, Lemma said. Following the discovery, investigators arrived at the family's home and found Ahmad and Ava, “who appeared at first to be sleeping.” They were later discovered to be deceased inside the home, Lemma said.

A cause of death for the children has not been announced at this time.

Hutto’s mother told authorities that her daughter struggled with depression throughout her life, “but there’s been nothing to indicate that she may act out with this level of violence towards her children" or die by suicide, Lemma added.

"I keep rethinking, and I wish things were different," Xavier continued in the fundraiser. "I’m torn, I’m broken and my heart is hurting."

GoFundMe has confirmed to PEOPLE that the fundraiser is verified.

Hutto's neighbor Gabrielle Buggs said the deceased mother was "just a person trying to make it through life," according to WESH 2.

Buggs said there was nothing to indicate any kind of violent tendencies from Hutto, even though at times she appeared overwhelmed.
