WHITTIER – Nearly 10 months after an 18-year-old Whittier man was shot to death by someone who asked for him at his front door, investigators Tuesday released a sketch of a man believed to be the shooter. Michael Reynoso was shot three times in the doorway of his home in the 7800 block of Vicki Drive on June 1, after the gunman asked Reynoso’s mother if her son could come to the door. She held Reynoso as he died on the front steps. Christina Reynoso pleaded Tuesday for the public’s help in solving her son’s slaying. “We need help, we need justice,” she said. “We need somebody to come forward. His life mattered.” Police based the sketch on the mother’s recollection of the man she saw when she opened the door at about 10 p.m. that night. He said his name was James and asked if Michael could come to the door, she said. Reynoso said she called her son, then went into the kitchen and, moments later, heard three gunshots. The gunman appeared to be in his mid-20s and had a dark skin color, she said. Los Angeles County Sheriff’s Department homicide Detective Rich Ramirez said despite his hard work on the case, few solid clues have turned up. He needs anyone who might know what happened that night to come forward, he said. The investigation has been difficult because potential witnesses have been too afraid to come forward, he said. Also, Michael Reynoso was known to have fought with several people in the neighborhood, Ramirez said. “There is no doubt there’s an element of retaliation associated with this murder – the lying in wait, knocking on the door, waiting for him to come to the door,” the investigator said. He believes the gunman acted alone. Meanwhile, Christina Reynoso said she cannot rest knowing her son’s killer remains free. “It’s so frustrating, I just can’t even tell you,” Reynoso said. “There is no closure for our family. Michael was the life of the family.” [email protected] (562) 698-0955, Ext. 3026160Want local news?Sign up for the Localist and stay informed Something went wrong.
