Slain Chechen terror suspect Tamerlan Tsarnaev was married to middle class college student Katherine Russell, 24.
The couple have a three-year-old daughter called Zahara
Tamerlan spent every weekend with Katherine's family at their suburban Rhode Island home
The devastated family of the wife of Boston bomber Tamerlan Tsarnaev say 'our hearts are sickened' by the terror and tragedy the young Chechen unleashed on America.
Tsarnaev has a three-year-old daughter called Zahara with Katherine Russell, 24, who converted to Islam for her husband, MailOnline can reveal.
And tonight, Katherine's parents, Judith and Warren issued an emotional statement following the terror attack that left three dead and 176 injured, saying:'Our daughter has lost her husband today, the father of her child.
'We cannot begin to comprehend how this horrible tragedy occurred. In the aftermath of the Patriot's Day horror, we know that we never really knew Tamerlane Tsarnaev
'Our hearts are sickened by the knowledge of the horror he has inflicted.'
The statement was read by Mrs Russell and when asked how her daughter was getting on, she shook her head and said:'There's nothing for me to say'.
The 26-year-old Chechen – who was shot dead by cops last night – was regularly seen at his wife's family home in Rhode Island.
And neighbours today spoke of their shock at waking up to see Katherine's home being raided by the FBI and cops before dawn this morning.
At 5pm today, Katherine was driven back to the house by a relative and flanked by two SUVs being driven by agents from the Department of Homeland Security.
Shielding her face, the young mother, wearing a dark-coloured top and sporting mousy blonde hair, was driven into the garage.
One of the Homeland security cars remained parked by the house. And asked if Katherine had been questioned, the agents refused to comment, but confirmed:'We are keeping an eye on the house'
A man, believed to be Katherine's father, Warren Russell, said:'We have no comment at this time.'
While a brunette, thought to be one of Katherine's two younger sisters, was earlier comforted by a friend, saying:'No comment.'
One neighbour told how Katherine - who also uses the last name Tsarnaeva - converted to Islam shortly after starting school at Suffolk University in Boston, saying she believed the couple were married.
