Tyler R. Gruber was 39 when he was killed during a violent home invasion at his Bay City, Michigan, residence. He was found dead on July 29, 2019. Reports say intruders forced entry through a window intending to commit robbery; during the break-in Tyler confronted one of the intruders, Brandon M. Dupuis, who had armed himself with a gun taken from the kitchen and fatally shot him.

Tyler grew up in Monroe, Michigan, and had moved to Bay City several years before his death. He was remembered as free spirited with an engaging smile and great loyalty to friends. The greatest joy in his life was his son, Trent; the two shared activities such as racing remote control cars, bike rides for ice cream, and video games.

Investigators arrested Dupuis and an accomplice, Devon J. Knights. Prosecutors relied on surveillance footage and witness testimony to show the pair planned the invasion to steal money and valuables. Both men were convicted of first-degree murder and related felonies and received life sentences without parole.

If anyone knew Tyler, his routines, or has information about the events leading up to that night, please come forward.
