Shana Grice, 18, was found by police officers at her house in the Portslade area of Brighton, after she had not turned up for work yesterday morning.
A colleague raised the alarm after being concerned about her whereabouts and Shana’s body was discovered at 9.45am that day
A man was later arrested in relation to her death and police have confirmed they are treating it as suspicious.
Shana’s devastated boyfriend Ash Crooke, 21, has described her as a ‘kind and caring’ person who was nice to everyone.
He said: ‘I don’t have my mobile at the moment – the police have got it – and obviously I don’t want to say too much about their investigation.
‘Shana was the nicest person you could ever wish to meet.
‘We have been together just over three-and-a-half years and we had plans. We had my uncle’s wedding on Saturday and dinner tonight.
‘We were planning to have children together next year and we were all ready to settle down, but now all that’s not going to happen.
‘She was supposed to finish work today and I was going to be meeting her then to go out for dinner.
‘I was with her yesterday morning, that’s when I last saw her because I stayed with her Wednesday night
‘I start work early and I have to leave hers at 7am in the morning to get ready.
‘She was awake and came to the door, we had a kiss and a cuddle and said goodbye, and then she locked the door after I left.
‘I was working in Saltdean and as soon as I knew something wasn’t right I knew I had to try and find her.
‘I jumped in my van and rushed back to hers as fast as I could.’
Ash explained the couple were planning on starting a family together next year.
He added: ‘She was a really kind girl, and she cared about everyone. I don’t know why anyone would do this to her because she wasn’t a nasty person and looked after everyone.
‘Everyone loves her, as you can see from the tributes on social media.
‘I’m getting a big Shana tattoo, it’s quite a big arm piece as a tribute to her.’
Ash continues to assist the police in their investigation, and will return to the force’s Lewes base to sign the statement he made to officers yesterday.
He added: ‘I think they are coming to get me later because I have got to go in and sign a statement.
‘They had their suspect in Brighton, and they didn’t want me there near him, so I went to Lewes to give my statement and now have to go back and sign it.’
He explained that Shana worked for delivery wholesaler Palmer and Harvey.
A Sussex Police spokesman said: ‘A man has been arrested on suspicion of murder following the death of a woman at an address in Mile Oak.
