She said he seemed friendly but also quiet and stuck to himself.
He was trying to get his life back on track, she said.
"I only saw him yesterday - he walked outside to get a parcel."
She didn't hear anything and the first she knew something was amiss was when she noticed an armed policeman standing on her property and was told the victim had been stabbed.
By lunch time about five police cars had gathered at Jasmine Pl in Cambridge.
Police officers had partially blocked the usually quiet suburban street and were only allowing residents access to their homes.
Police tape had also been strung across the driveway of a property.
Bewildered neighbours gathered outside to see what the commotion was.
Residents said the family who lived at the property were usually quiet.
Shortly after, a tow truck arrived to remove a beige sedan parked in the driveway.
