LAKELAND, Minn. (CBS/WCCO) Friends of Jacob Campbell and Lisa Grijalva, two Minnesota teens whose bodies were found Tuesday night in an apparent murder-suicide, say the teens may have recently ended their long-term relationship - but can't believe that could have led to murder.

The Hennepin County Medical Examiner's rulings on the two teens suggests Jacob killed Lisa before turning the gun on himself. On Thursday, officials ruled Lisa's death a homicide and Jacob's death was ruled a suicide.

The medical examiner wouldn't elaborate on the manner of their deaths, but earlier this week, Sheriff Bill Hutton said the two sustained apparent gunshot wounds. Deputies responding to the scene found a long-barreled weapon near one of the two teens.

Their bodies were discovered near a heavily wooded area not far from a footpath at around 7:30 p.m. Tuesday.

Friends told CBS affiliate WCCO that the two had been dating for a few years, but may have recently ended their relationship.

On his MySpace page, Jacob's last update on Oct. 11 states, "very regretful, single," with his mood status as "sad."

But still, friends said they couldn't imagine Jacob would've been heartbroken enough to take his own life or hers.

Jacob's family released a statement to WCCO claiming their son was a "cheerful spirit" who was kind and always quick with lighthearted joke.

"He loved to spend time with friends, including hours on the Ultimate Frisbee fields, his time with the Cub Scouts and Boy Scouts, and working on various service projects at church and with other groups throughout the community," the statement said. "Family was of utmost importance to Jacob, whether it was the average day with his parents, brother and sister, or at larger family events where he loved to hang out with his cousins.

WCCO reported that Lisa's family asked for privacy.
