A man charged with murder over the stabbing death of 17-year-old Melbourne girl Masa Vukotic will appear in court again today.  During a brief out-of-session court hearing last night Sean Christian Price was charged with murder and six other offences in relation to a string of earlier allegedly violent incidents.  Homicide detectives spent much of yesterday questioning the Albion man after he fronted up at Sunshine police station about noon.  The 31-year-old was taken to the St Kilda Road police complex and later charged with seven offences, including one count of murder stemming from Tuesday's fatal stabbing in Doncaster.  A suspect in the alleged murder of a Melbourne teen is taken to the homicide unit at St Kilda Road police headquarters, and Masa Vukotic. (9NEWS)  He is also alleged to have carried out a violent crime spree in Sunshine yesterday morning and police charged him over an alleged rape, two assaults, a robbery and an attempted carjacking.  Police allege he assaulted a 26-year-old man on a footbridge and stole his mobile phone before attempting to carjack a 77-year-old woman.  Mr Price is also accused of going into a business on Harvester Road and approaching a woman before allegedly becoming violent and physically and sexually assaulting her.  He wore a blue disposable jump suit, and had bare feet, as he was brought before bail justice Ben Czerniewicz.  The accused man was also handcuffed, and slouched in his seat.  "There are a total of seven charges against you, are you aware of the charges?" Mr Czerniewicz asked him.  He was remanded in custody to appear in the Melbourne Magistrates Court today.  When Mr Czerniewicz read out the accused man's date of birth, Mr Price misheard it as a much earlier year.  "Are you a judge? I must look pretty good for my age," the accused man said.  Tuesday's alleged murder has prompted an outpouring of grief from the community, with the boyfriend of the teen penning an emotional farewell to the young victim.  "My dear love, you will always be in my heart," he wrote in a letter laid among flowers at the crime scene.  A Facebook photo of Masa Vukotic.

"I love you, my dear, and I always will remember you.  "Love from your lover, Tim."  Tributes flow for slain teenager  By 7pm Wednesday night, more than 100 people stood in silence in the park as they paid tribute to the Canterbury Girls' Secondary College student known affectionately as "Marci".  A former tutor of the teen spoke to 3AW radio today saying she was such an impressive student he once joked she would be a prime minister one day.  Glen Nicholson, who tutored Masa and her brother a few years ago, told 3AW she was a "vibrant young woman" who had a "good heart, integrity and thought big picture".  "(She) loved life. I was just shocked when I discovered that she'd been one of my students a few years ago ... it was one of the worst nights' sleep I ever had.  "I even joked to her, 'you'll be prime minister one day'. She had all those qualities."  "She was always smiling ... she'd walk into the class and have a conversation with me rather than just say hi. (She'd) ask me how I was. We talked about world issues. she was a very intelligent girl but funny and (she had) just a wonderful smile."  She had been walking with headphones on in daylight when she was allegedly attacked.  Police described the park Masa was allegedly murdered in as a small enclave in a relatively quiet street.  Another man held by police on Wednesday afternoon, who matched the suspect's description, has been ruled out as having any involvement.  The murder weapon has not been found, and the man in the footage is seen to be carrying a white plastic bag that may have contained it.
