The Virginia Tech Police Department has grown since the April 16 campus killings.
After the shootings, Tech approved just over $487,000 in new funding for the police department to pay for 11 new officers. The hiring will bring the total of sworn officers on campus to 50.
Chief Wendell Flinchum said the department received more calls last semester, which he attributed to the campus being edgier since a student gunman killed 32 students and teachers, then himself.
Flinchum, who has been with the department since 1983, had been chief for less than a year last April when the shootings occurred.
The university is in the design phase for a public safety building. If funding is approved, the building will house Tech's police, rescue squad and emergency management operations.
