Cops in Wyoming, Mich., say Eric Santiago opened fire on another vehicle while driving through a gas station parking lot, in an attempt to kill the driver.
Santiago's younger brother, Juan Enrique Reyes, is believed to be the triggerman who killed 22-year-old Ryan Pollok in September 2007.
Douglas ''Ryan'' Pollok, 22, was shot to death while standing outside of a house party in the early morning hours of Sept. 30, 2007.
Cops say Santiago may have a tattoo like the one pictured here, on his right hand webbing.
His brother, Juan Reyes, has one that looks similar to this.
This candid photo of Ryan (bottom left) was taken at a birthday party for two of his friends, in the hours before his shocking death.
On Sept. 29, 2007, Ryan Pollok celebrated his friends' birthdays at a party in Grand Rapids. His buddies remember him as a carefree and fun-loving young man.
Ryan and Stephanie were happily engaged and looking forward to spending the rest of their lives together. Their wedding was slated for September 2008.
