At approximately 10.20pm, April 18, police received reports of shots fired on the MIT campus.

Authorities launched an immediate investigation into the circumstances of the shooting. The investigation determined that two males were involved in this shooting.
A short time later, police received reports of an armed carjacking by two males in the area of Third Street in Cambridge.
