After police in Charlottesville searched the apartment of a UVA nursing assistant seen by eyewitnesses with his arm around Hannah Graham's waist on the night she went missing, the Daily Mail reports that authorities say they have no probable cause to arrest him.

In an exclusive story with the Daily Mail Online, the man is identified as Jesse "LJ" Matthew. The 32-year-old nursing assistant who works at UVA hospital admitted to buying Hannah Graham drinks but denies having driven off with the 18-year-old in his car.

Via the Daily Mail:

Matthew's grandmother, Christine Carr, told MailOnline on Saturday: 'I have been talking with his mother.

'He said he went his way and she went hers. He told his mother he bought her some drinks. He said she did not get into his car.

'The girl went her way and he went his.'

Matthew was spotted by eyewitnesses with his arm around Graham's waist and has since had his apartment raided and his car seized. Investigators are undergoing a forensic search of his apartment.

Graham has been missing since last Saturday. Over 1,000 volunteers have joined the search to find her.
