The bodies of a mother and her seven-year-old son have been discovered in their west London home.
Sinead Higgins, 37, and Oisin O’Driscoll were found at the address in Ruislip, on Wednesday morning after friends and neighbours raised welfare concerns.
Detectives from the Homicide and Major Crime Command are investigating and next-of-kin have been informed.
Four days before her body was found, registered nurse Higgins tweeted: “The future looks very” followed by the emoji of a tornado.
One neighbour told The Sun: “I last saw Sinead on Sunday, she’d obviously been to Sainsbury’s and had a few bits in her bag. She didn’t talk, she had her head down.
“I last spoke to her about a month ago for around an hour. She was desperate, she said everything was going wrong.”
Detective Inspector Dave Bolton, from the Homicide and Major Crime, said: “The investigation is at a very early stage but enquiries so far lead us to believe there is a likelihood that the tragic events that led to the deaths do not involve a third party.
“We are appealing to anyone who has any information to come and speak with us.”
