A convicted felon is facing attempted murder charges after he allegedly stabbed an Oregon man for no apparent reason.

The Oregonian reported that Michael Lee Williams (pictured left), 33, is accused of stabbing Pedro Shroyer, 38, multiple times outside of an Old Town apartment building Monday night. Surveillance cameras caught the victim attempting to flee following the stabbing and the suspect catching up with him and continuing the attack, according to court documents obtained by KOIN.

Portland police said Wednesday that Shroyer is in critical condition and sustained life-threatening injuries, The Oregonian also wrote.

Authorities don’t believe Williams and Shroyer knew each other. Police called the attack “completely random,” according to KOIN.

Williams was arrested in connection with a separate incident a day later. The 33-year-old is accused of assaulting a bus passenger, taking their wallet, and breaking a bus window.

The Portland Patch reported that authorities tied Williams to the May 8 stabbing while he was in custody.

On Tuesday afternoon, Williams purportedly “cold-cocked” an unsuspecting inmate in the jail’s open holding area. He then allegedly became aggressive with corrections deputies, leading them to use force.

KOIN reported that Williams has a slew of prior convictions: five felonies, nine misdemeanors, and four parole violations. The convictions took place in Oregon and Washington, where his crimes included robbery and taking a motor vehicle without permission.

Williams was charged with attempted murder, first-degree assault, and unlawful use of a weapon. On Friday, he was also charged with third-degree robbery, fourth-degree assault, and interfering with public transportation for the May 9 incident.

The suspect pleaded not guilty at his arraignment on Friday. His next court date is scheduled for May 22.
