A Washington state man wanted for attempted rape and kidnap has been arrested in Missoula.

33-year-old Aaron Michael Sparks is facing three felony charges after he allegedly attacked a co-worker as she walked to her car after work.

Court documents say he used a stun gun to try to abduct her.

It remains unclear how he ended up in Missoula, but court documents indicate he's hospitalized with self-inflicted wounds.

Sparks will be in court later this month.  NBC Montana will be there to the get details.
