Federal officials on Tuesday released transcripts of video recordings left behind by Claudio Manuel Neves Valente, the Portuguese national responsible for the senseless murder and mass shooting at Brown University and targeted killing of an MIT professor in Brookline.

On Dec. 13, gunman Neves Valente, 48, entered a study session in a Brown academic building and released a hail of gunfire on students gathered there, killing Ella Cook and 18-year-old freshman MukhammadAziz Umurzokov and wounding nine others.

Two days later, Neves Valente fatally shot Massachusetts Institute of Technology professor Nuno F.G. Loureiro at Loureiro’s Brookline home.

“Neves Valente showed no remorse during the recordings,” federal officials said in a release accompanying the transcripts.  “On the contrary, he exposed his true nature when he blamed innocent, unarmed children for their deaths at his hand and grumbled about a self-inflicted injury he suffered when he shot the MIT professor at close range. Our investigation into the motives behind Neves Valente’s heinous acts will continue.”
