With her cousin dead and her boyfriend suspected of the shooting, a distraught Jayna Emerson, 17, of St. Paul, struggled to get out the words Monday.
"We know what happened; we know you're scared," she said in an appeal to boyfriend Alfredo Gutierrez-Gonzales, 19. "Please turn yourself in so we know you're OK and we can see you."
The public plea came in front of the West Side house where Jacob MacKenzie, 15, a quiet, well-liked 10th-grader, was shot to death early Sunday, leaving not just his family, but his teachers at nearby Guadalupe Alternative Programs, to mourn him.
As for the suspect, known to friends as Freddy, Emerson described him as a "great boyfriend" determined to "turn his life around."
Earlier this year, Gutierrez-Gonzales pleaded guilty to terroristic threats in connection with a MySpace message in which he bragged of owning an AK47 assault rifle and an Ingram Mac 11 assault pistol, and also had claimed membership in the Brown Pride street gang, according to Hennepin County District Court records.
The message, sent to a man then dating a woman identified only with the initials "J.E.," cautioned the recipient to watch his back, and to keep a close eye on his stepdaughter, too, "cuz it hurts when someone you love goes missing," the MySpace message said.
Police spokesman Peter Panos said Gutierrez-Gonzales also had a juvenile criminal record in Ramsey County, but he had no details. Police still are trying to determine, Panos said, what led to Sunday's shooting, which occurred about 12:25 a.m. and left MacKenzie dead on the family's front porch.
"As far as [if it was] an argument or if it was just an accident -- we just don't know," Panos said. "That's why we need to talk to Freddy. We need to hear his side of the story."
