A teenage murder suspect who authorities say escaped from police custody at an Ohio hospital and abducted a 70-year-old woman before he was captured is now charged with kidnapping and other counts.

The 17-year-old had been charged with a juvenile count of murder in the Jan. 14 shooting of a Fairborn man, whom the teen and an accomplice had robbed of 38 rifles, various other firearms and a large amount of ammunition, authorities said.

Juvenile charges of escape, aggravated burglary, kidnapping and auto theft were added Monday, Megan Farley, an assistant prosecuting attorney in Clark County, said Tuesday. Farley says the prosecutor's office is seeking to have the teen tried as an adult.

It couldn't be immediately determined whether the teen has a lawyer.

The latest charges stem from the teen's Friday night escape from a hospital where he was transferred from juvenile detention for an ankle injury that authorities believe was faked.

Clark County Sheriff Gene Kelly told The Springfield News-Sun that the teen had scoped out the hospital last week after he scraped his lip doing pull-ups.

"He had looked the situation over, developed his plan," Kelly said.

The sheriff's office wasn't notified by juvenile authorities of the hospital trips, and the teen escaped when his shackles were removed to fit him with a pair of crutches, authorities said.

The teen was caught Saturday morning after authorities say he forced a 70-year-old Springfield woman at knife-point to drive him to Fairborn, where police later arrested him. The woman told authorities the teen held her hostage.

The teen's alleged accomplice in the slaying of William Henson, Robert Winbush, 18, has been indicted on charges of aggravated murder, felonious assault, theft and related offenses, Farley said Tuesday.

Winbush's attorney, Shawn Thomas, didn't immediately return a call for comment.
