Neighbors, whom we spoke with, are calling the allegations against 27 year old Matthew Hyrup troubling.
"It's scary and I live so close. I'd seen them a couple of times. I didn't even know they had kids," said a neighbor who didn't want to be identified.
Police say Hyrup beat his stepson repeatedly and even penetrated the 18 month old boy.
He faced a judge earlier this afternoon.
"I see 3 or 4 cops and I was like looking and a lady was carrying a baby and it didn't look like it was moving," described the neighbor.
The youngster was flown to Doernbecher's Children's Hospital in Portland. At last check, he was listed in critical but stable condition.
"The victim had injuries internally and externally," said Lieutenant Mike Budreau with the Medford Police Department.
Hyrup married the boys' mother two weeks ago. The marriage certificate list Matthew Hyrup as the 'groom' and 21-year-old Stephaine Raeanne Hyrup as the 'bride.'
This isn't Matthew's first run in with the law. We found charges dating back to 2006. He was convicted of driving under the influence, driving while suspended, unlawful use of a firearm, and possession of meth.
"He's currently on probation for dangerous drugs; methamphetamine specifically. And that will lead to questions of hey, was drugs involved? That does not appear to be the case," said Budreau.
As for the boys' mother, police say she was not home at the time of the assault. Authorities tell us she is in Portland monitoring her son's progress.
