A 19-year-old woman believed to have been shot dead by her father was studying to be a midwife at the University of Northampton, according to reports.
Three people died in a shooting at Spalding's Castle Sports Complex on Tuesday morning.
They have been named locally as Claire Hart, 50, and her daughter Charlotte, 19, who were believed to have been killed by husband and dad, Lance Hart, 57, who also died in the incident.
Charlotte was studying at the University of Northampton but was home for the summer holidays.
Jess Wright was among coursemates who paid tribute to her.
She said: "Rest in peace Charlotte Georgia Hart.
"I'm sure I speak on behalf of the whole Midwifery cohort, you were so lovely and will be missed by all.
"Such a cruel world."
Kerrie Mckim added: "Lovely girl who wouldn't harm a fly. Such a tragedy, RIP."
Neighbours told how police swooped on the family’s the home in Moulton in Lincolnshire around 10am – an hour after they were shot.
Officers have since been raiding the property where the family lived for the last seven years.
A neighbour known only as Peter, described Lance, who is understood to have worked at a nearby builders’ merchants, as “the nicest guy you could ever meet” and said he “would do anything for anyone”.
Another neighbour described the Harts, who are believed to have got married in 1990, as the “loveliest couple ever”.
The woman, who did not wish to be named, said: “They were an absolutely lovely family.
“They were the loveliest couple ever. We don’t know them well but wave to them when we see them."
