From all accounts, the two-vehicle crash that brought Portland Police Bureau (PPB) East Precinct officers to the Wilkes neighborhood on December 12 at 10:42 p.m. was horrendous.

Officers who were first at the location on NE Halsey Street, just west of 162nd Avenue found two badly-wrecked vehicles; and arriving paramedics determined that two occupants of one vehicle were deceased.

Ambulances take those seriously injured in this wreck to a hospital.

“Two other patients [from the other car] were seriously injured, and were transported to the hospital by ambulance,” reported PPB Public Information Officer Derek Carmon.

Again, the PPB Traffic Division Major Crash Team (MCT) came out to lead the investigation into this smashup, and closed NE Halsey Street from 160th to 162nd Avenue. “One vehicle was in a parking lot, with significant intrusion to the driver side of the car as a result of a side-impact, often called ‘T-bone’ collision; both the driver and the passenger in that vehicle were deceased.

“The second vehicle had significant damage to the front end; and, a passenger in that vehicle was pinned in and had to be extracted,” continued Carmon. “Further, witnesses and officers saw other people, possibly associated with the crash, leave the area before they could be stopped.” That made the crash a hit-and-run.

PPB MCT investigators found businesses in the area with very good camera systems and allowed video to be collected. “The video indicated that speed was a likely factor in the crash, and also, investigators confirmed that the driver had, indeed, fled the scene,” Carmon said.

Further, the vehicle the suspect was driving was later reported stolen from the Lloyd Center area. It’s unclear how they discovered it, but investigators learned that the fleeing driver was by then in a hotel near the Lloyd Center.

“At the hotel, investigators contacted and interviewed the suspect, who had blood on his sweatshirt; the suspect subsequently confessed to being the driver in the collision, and he was taken into custody,” informed Carmen.

The suspected driver, 18 year-old Tyviant Tilden Mancilla, was taken to a police precinct office for further questioning; and then to a hospital to be evaluated for possible injury, due to airbag deployment.

“This is the 50th Major Crash Team callout of 2020 and the 54th and 55th fatalities of 2020,” concluded Carmon.

Mancilla was then to and booked at the Multnomah County Detention Center (MCDC) the morning following the crash, December 13, at 9:45 a.m.

During his arraignment, Mancilla learned he’d face four felony charges, including two counts of Failing to Perform the Duties of a Driver (Serious Injury/Death), and, two counts of Failing to Perform the Duties of a Driver. The combined bail for these charges totaled $50,000.

Suspect also faces Attempted Murder charges
But that was not the end of this story. While jailed at the MCDC, Mancilla learned he would also be facing charges relating to another case – one of attempted murder.

“The attempted murder and vehicular homicide cases are unrelated,” stated Multnomah County District Attorney’s Office spokesperson Brent Weisberg.

“The Grand Jury returned its secret indictment on November 11, 2020, which automatically triggered a warrant; attempts to locate and arrest Mancilla would have been made by law enforcement,” Weisberg told East Portland News.

So, on December 15, additional felony charges were filed against Mancilla, including two counts of Attempted Murder II, two counts of Attempted Assault I, three counts of Unlawful Use of a Weapon, and one count of Unauthorized Use of a Motor Vehicle (a felony vehicle theft charge).

Mancilla’s combined bail for these additional charges total an additional $560,000. And he’s still incarcerated in the MCDC.
