The deaths Sunday of a Tipp City man and his 18 year old son were ruled suicides that took place as part of an agreement between the two, Tipp City police said.

Mark Rittenhouse, 48, and his son Ryan Rittenhouse, 18, were found around 2 p.m. in the backyard of their North Westedge home. Miami County Coroner William Ginn said the deaths were suicides.

"This is something they entered into together and willingly," Police Detective Sgt.  Chris Graham said of the deaths by hanging. Autopsies were conducted Monday at the Montgomery County Coroner's Office.  Toxicology reports won’t be available for several weeks.

A neighbor called police after seeing the bodies, Graham said. There was no evidence of criminal activity or foul play, he said.

A note was found near the bodies, but Graham said he could not release any details.

Those who knew the Rittenhouses told him that the father and son “were very close,” Graham said.

Ryan Rittenhouse graduated from Tippecanoe High School in May. He was the first place winner of the state boys’ division one high school bowling tournament last spring.

At Tippecanoe High School Monday guidance counselors were available to talk with students and staff, Liz Robbins, schools communications director, said.

A candlelight vigil in memory of Ryan Rittenhouse will be held by Olde Tippecanoe Ghost Walks Saturday, Oct. 31, at 10 p.m. at Royal Crest Agency back parking lot. All ticket proceeds from the ghost walks will be donated to the family to help defray final expenses. Donations for the family also will be accepted by Browse Awhile Books, 118 E. Main St.

Those wanting to attend the candlelight vigil only are asked to meet behind Royal Crest Agency at 9:45 p.m.
