This is the first picture of a woman knifed to death in a double stabbing at a flat as police urgently hunt a murder suspect.
Yolanda Saldana Feliz, 53, was attacked along with another 30-year-old woman in Windmill Lane, Stratford at 3.30am on Sunday.
Murder detectives on Wednesday released an image of Miguel Angel Alvarez Florentino, 38, who is known to frequent east London, as someone they would like to speak to in connection with the murder.
The second woman was taken to hospital where she is continuing to receive treatment. Her injuries have been assessed as not life-threatening.
A post-mortem examination took place on Tuesday and gave the cause of Ms Feliz’s death as stab wounds.
DI Aytac Necati, from the Met’s Specialist Crime Command, said: “Our thoughts very much remain with Yolanda’s family and friends as well as the family and friends of the injured woman, who remains in hospital recovering from her serious injuries.
“We remain determined to bring the person responsible to justice and we have been working around the clock during this fast-moving investigation.
“We have carried out a number of enquiries, including reviewing hours of CCTV, door knocking and forensics. However, we are now calling on members of the public to help us urgently trace Miguel Angel Alvarez Florentino who we want to speak to in connection with the incident. He may be going by a different name.
“If you have any information on where he might be, please contact us without delay. If you see him, please do not approach him but call police immediately on 999.”
Chief Superintendent Simon Crick, who is responsible for the policing of Newham, said: “I remain shocked and saddened by this incident and my thoughts and sympathies are with Yolanda’s family and friends. I also wish the injured woman a speedy recovery.
“I know this has caused a great deal of concern for the community, but we believe the suspect was known to the victims and he is not believed to be a threat to anyone else at this time.
“My colleagues from the Specialist Crime Command have been working tirelessly to bring the perpetrator to justice. I would now urge the community to help them by getting in touch with any information they may have – including the whereabouts of Mr Alvarez Florentino who they urgently want to talk to.
