PRESTON, Minn. (AP) _ A man was convicted Friday of killing his 3-year-old son by taping him to a tree in the woods as a way to win back his estranged girlfriend.

Harold Kramer Jr., 27, was convicted of second-degree intentional murder in the boy's death last May. He faces up to 40 years in prison when sentenced April 17.

The jury acquitted Kramer of first-degree murder but also found him guilty of felony murder and child endangerment.

Eight days after Kenny disappeared, police found the boy's body _ still dressed in his red sleeper _ in a garbage bag. He was bound with duct tape to the base of a tree near the family's home in southeastern Minnesota.

Kramer was accused of leaving his son in the woods in the middle of the night to die as part of an effort to win back his estranged girlfriend.

During the police investigation, Kramer confessed to the killing, but the defense contended the confession was coerced. At the trial, he testified that he did not kill his son.

Defense attorneys argued that Kramer was the victim of a drug deal gone bad and a sloppy investigation.

After the verdict, defense attorney Candace Rasmussen said she still believed he did not kill his son. ``He loved his son,'' she said.

The prosecution argued that Kramer provided police with facts only the killer would know.
