The mother of the 37-year-old Concord man who police said lit his twin sister on fire Thursday is thanking the people praying for her family.

In a public Facebook post, Rebecca Crawford wrote Friday that she’s grateful her daughter and grandsons are alive and that her friends and family have been so supportive.

“Thank you to all and continue to pray for us,” she said.

Police detective Sgt. Sean Ford said investigators are trying to piece together what led to such a heinous act.

“We’re still trying to answer those questions ourselves,” he said.

Dwayne Crawford, of 66 Woodbine Ave., told police outside the scene of his burning home about 3 a.m. that he doused his sister in gasoline and ignited her, according to Officer Brendan Ryder’s sworn affidavit. Her two children were in the home at the time.

Ryder wrote that Crawford “displayed very little affect and expressed no emotion” as he confessed.

A lawyer for Crawford on Friday entered a not guilty plea and waived arraignment on charges including attempted first degree murder.

Crawford is facing five felonies in all and remains held without bail at Merrimack County jail, police said. He has a probable cause hearing scheduled for Dec. 28 at 8:30 a.m at Concord’s district court.

His sister, Tamika Crawford, was burned on most of her upper body, police said. She was transported to Concord Hospital, then to a Boston hospital, to be treated for third-degree burns.

Ford said Friday that she was still in Boston in “serious condition.”

The sergeant said he couldn’t release any more information about the case.

“It’s still very much an ongoing investigation,” he said.

Rebecca Crawford didn’t respond to attempts to reach her Friday.
