Police Release CCTV After Coventry Murder
Police have released CCTV footage of two men who may hold votal information into the death of a Coventry woman in February
Tracy Snook-Kite, 52, was found with head injuries by the ambulance service inside her house on Monks Croft at around 6.40am on 23 February.
Her house is located at the edge of an alleyway and detectives have released footage of two men seen walking through the alleyway on the night it is believed Tracy died.
Detective Inspector Harry Harrison, from the Major Investigation Review Team, said: "We continue to piece together the events of the night Tracy died and specialist officers continue to view hours of CCTV footage for any further clues.
"We are keen to trace the two men in the footage who were seen walking along the alleyway from Daintree Croft to Monks Croft minutes after Tracy used the same alleyway to walk home.
"This was the night of the England v Ireland Six Nations rugby match and these men may have been on the way home from a night out.
"It is really important that they come forward so we can establish if they recall anything that may help our investigation.
"I would stress that these men are not suspects but could hold vital information that may assist our case."
52 year old Anthony Stanyer was charged with Tracy’s murder and is due to appear at Birmingham Crown Court on Friday 9 May.
Two men from Birmingham remain in custody after a search for accomplices to the Westminster terror attack has seen 11 arrested this week.
