Aasiya Hassan The founder of a US Muslim TV network has been charged over the beheading of his wife, media reports say.
Muzzammil Hassan, 44, is accused of second degree murder of Aasiya Hassan, whose body was found last week at the TV station in New York state.
Both Mr Hassan and his wife worked at Bridges TV, a station aimed at countering stereotypes of Muslims.
Authorities said Mrs Hassan, 37, had recently filed for divorce. The couple had two children, aged four and six.
Bridges TV, a satellite-distributed news and opinion channel, was founded by Mr Hassan in 2004 and was based in a suburb in Buffalo, in upstate New York.
Mrs Hassan had filed for divorce after enduring previous incidents of domestic violence, her lawyer told the Buffalo News.
In a statement on its website, Bridges TV said it was "deeply shocked and saddened by the murder of Aasiya (Zubair) Hassan and subsequent arrest of Muzzammil Hassan".
A family court hearing was due to address the future of the couple's two children.
Their grandparents have travelled from Texas and Pakistan to attend the hearing, John Tregilio, a lawyer for the children, told the Buffalo News.
Mr Hassan also has two other children, aged 17 and 18, from a previous marriage, according to reports.
