Kayla Gomez-Orozco's body was discovered in a well Bullard, Texas, a few miles from where she went missing

The man accused of abducting and killing a 10-year-old girl is a relative who is in the United States illegally, reports suggest.

Gustavo Zavala-Garcia is in custody on an immigration hold after Kayla Gomez-Orozco's body was found in a well next to his home in Bullard, Texas, on Saturday night.

He is believed to be the last person to have seen the youngster alive. Police also believe he caused her death.

A law enforcement source told KETK, he somehow got back into the United States after being deported for committing a violent crime in 2014.

Jail records indicate he served 30 days behind bars for assaulting his wife.

He is in the Smith County jail with no possibility of bond.

Kayla was last seen on Tuesday at the Bullard First Assembly Church where she was attending a prayer service with her family.

Smith County Sheriff Larry Smith told the TV station: 'A family member resides at the residence that we conducted the search where the body was recovered.

'He voluntarily accompanied law enforcement officers to be interviewed. Upon the completion of the interview, a federal immigration detainer was issued for his detention.

'He is now in the Smith County jail, without any possibility of making bond at this time.'

Zavala-Garcia is married to Kayla's cousin, the Tyler Morning Telegraph reported.

His wife Esther Zavala told the newspaper her husband and daughter went to the Tuesday prayer service, which she didn't go to.

She said: 'Kayla bent down to hug (my daughter) and said, I'll see you Friday. My husband buckled her up, and said, "We're leaving."

'(Kayla) didn't come outside. She is scared of the dark. She stayed in the lobby area.'

Citing court records, the newspaper reported that Gustavo Zavala-Garcia pleaded guilty to assaulting his wife and received a 30-day county jail sentence two years ago.

Authorities initially believed that Kayla may have been snatched by a stranger.

Officers said she was in 'grave danger' when she first disappeared.

'However, please remember that there is a family involved, and respecting this family who is in more pain than you imagine needs considered first and foremost. Thank you for your respect of the family at this time.

Cherokee County Sheriff James Campbell has described Kayla as a 'sweet little girl, just as cute as she could be'.

When she first went missing, he said they had no idea why she would have been abducted.

Kayla, who has black hair and brown eyes, was wearing a black t-shirt and a peach-colored skirt when she was last seen on Tuesday night.
