"It is not women and girl's responsibility to make themselves feel safe"
In an interview with ITV News, women's safety expert Lyn Gooding issued advice for people on how to stay safe.
But she stressed ultimately it should not be women's and girls' responsibility to make them feel safe.
Lyn Gooding, CEO of First Light Southwest, said Bobbi-Anne's case is "absolutely devastating".
"The family of that young girl must be devastated right now; our heart goes out to them. Nothing people can do or say can make them feel any better at the moment," she added.
"The community of Plymouth, I send my heartfelt condolences."
Speaking of what steps women could take to try and ensure their safety in the winter months, Ms Gooding said: "First and foremost, I would like to say that it shouldn't be women and girl's responsibility to make themselves feel safe. It is the usual tips at the moment.
"Let people know what your plans are and what times you expect to be in places.
"Also, plan your route and make sure you stay in brightly-lit public areas. If you are going long distance maybe try booking a taxi service. Always carry an alarm.
"Another thing I would say is that do not be afraid to draw attention to yourself if you feel like you are in danger.
"Always look for other people if you are really worried. Make noise and call-out, and that may actually put somebody off if they are contemplating causing you harm."
'There are lots of apps out there that can help you feel safe'
She added there are a number of ways using your phone could help people feel more comfortable, saying apps could provide more security.
"Hollyguard is a good app so consider downloading one of those to make you feel safe, and if you really feel in danger, don't be afraid to call the police."
