January 2013: Boise State defensive end Sam Ukwuachu is named a 2012 Freshman All-American by multiple outlets after a 4.5-sack debut season.

May 2013 and thereabout: An incident happens that does not result in criminal charges, but that will later draw the interest of Waco prosecutors, as reported on by the Waco Tribune-Herald in 2015:

Records from Boise State show that Ukwuachu, who reportedly was drinking and using drugs, and [a woman with whom he reportedly had an abusive relationship] were involved in a dispute. Ukwuachu broke a window and cut his arm, requiring medical treatment and prompting a Boise police investigation.

Two years later in a Waco, Texas court, a former Boise police officer would testify that even Ukwuachu's roommate was afraid of him.

Texas Monthly would report:

Handwritten notes in a document from a Boise State source also refer to times that Ukwuachu would get verbally abusive over 'small irritants' like a spilled drink, and note that the woman he lived with acknowledged that she would 'probably not' admit it if the abuse were physical. It ends with the words 'NOT healthy relationship!'

It's unknown whether Baylor ever received this document.

May 7, 2013: Boise State dismisses Ukwuachu for violating team rules. When head coach Chris Petersen had been asked a month prior if Ukwuachu would play that season, the coach had said, "Yeah, he's just handling some personal stuff."

May 21, 2013: Former Texas high school star Ukwuachu -- who'd once scored a touchdown in a state championship when 10 defenders didn't realize the ball had been snapped -- confirms he's transferring to Baylor, saying, "[Petersen] really helped me to where I wanted to go. Things just didn't work out up there.''

August 2013: Texas Monthly would report: "Chad Jackson, a senior associate athletic director at Baylor, was informed by John Cunningham, an associate athletic director at Boise State, that Ukwuachu's previous school did not support any waivers to get the player back on the field."

Schools do sometimes help dismissed players gain eligibility at new programs, but it's hard to say how commonly.

October 20, 2013: From a 2015 Deadspin story:

The call came to Waco police from Baylor Scott & White hospital saying a woman had been sexually assaulted earlier in the morning. Police began their investigation, and the woman identified the attacker as someone she knew, incoming football player Sam Ukwuachu.

March 2014: Waco police turn the investigation over to the district attorney's office, according to the Waco-Tribune Herald.

June 25, 2014: Ukwuachu is indicted by a grand jury on two counts of sexual assault against a Baylor athlete. Baylor will soon be ranked No. 10 in the preseason AP Top 25, and somehow, no one really hears about this situation involving one of its potential players.

Throughout: From Texas Monthly:

Per testimony from her counselor at Baylor, Cheryl Wooten, Jane Doe was diagnosed with post-traumatic stress disorder following the encounter. When Doe sought to avoid Ukwuachu on campus, the school didn't move him out of the classes or tutoring sessions the two shared—instead, she had to adjust her schedule. Eventually, Doe found her own scholarship reduced, and she transferred to another university after the 2013-14 school year.

It's not explicit in the Texas Monthly story if that scholarship reduction and transfer happened for any reasons in addition to avoiding Ukwuachu, though the victim's father testified as follows:

He said the assault hindered her recovery from a knee injury and contributed to her losing her scholarship at Baylor. — Tommy Witherspoon (@TSpoonFeed) August 21, 2015

August 5, 2014: Many notice Ukwuachu has already sat out his NCAA-mandated transfer season, but is still not on Baylor's fall roster. Baylor defensive coordinator Phil Bennett, at the time:

#Baylor junior DE Sam Ukwuachu, a Boise State transfer, has "some issues" to deal w/ per Bennett. "Will not practice for awhile." — Craig Smoak (@CraigSmoak) August 5, 2014

August 5 is when, ideally, someone in Waco media would've begun digging into those issues. But the fact that Ukwuachu never appeared on Baylor's roster could've meant that later routine police records checks would neglect to include his name.

June 3, 2015: Bennett says on a radio show that Ukwuachu is "expected" to finally join the team in July.

This is how coaches talk about roster things to the media, even disturbing things.

August 5, 2015: The Waco Tribune-Herald reports Ukwuachu's trial on two counts of sexual assault will begin on August 17. Ukwuachu also now holds a bachelor's degree from Baylor. This is the first almost anyone outside of Waco has ever heard of the allegations.

August 6, 2015: Baylor head coach Art Briles:

That's been an ongoing situation for, I don't know, a year and a half probably, and we've been real sensitive to the process. We've sat back and waited for it all to take shape and see what the outcome is. So I like the way we've handled it as a university, an athletic department and a football program.

That part about the Bears waiting to see the outcome seems true. Ukwuachu never suited up for the team, despite how badly the university appears to have handled all of this. (Deadspin breaks down BU's ineffective internal investigation.)

August 7, 2015: At 3:22 p.m. local, a district court grants a gag order on the case. Deadspin later reveals the document and walks through the bizarre difficulty of obtaining information about the case from any department, whether a department of law enforcement or of Baylor University.

Most of what happens at Baylor, a private school, is not subject to the Freedom of Information Act.

August 18, 2015: From the victim's testimony, via Tommy Witherspoon's summary:

She is 5'2. Ukwuachu is 6'4 and outweighs her by a lot. He forcefully turned her over and took off the rest of her clothes, she said. ... He said, 'This isn't rape,' during the assault, she testified. ... She went home for a week after the assault and said it was hard for her to be around males, including her brother and Dad. ... 'Every time I saw him my heart would just sink, like he still had control,' she said, talking about seeing Ukwuachu on campus afterward.

August 20, 2015: From the final day of the trial, again via Witherspoon:

Prosecutor Robert Moody: 'What was your favorite part about the event? Was it when she was screaming no, stop?' 'I would not do that. I respect women,' Ukwuachu said. That response opened the door for Moody to ask him if he beat his girlfriend at Boise State. Ukwuachu denied he ever hurt a woman. 'Why did you have to take anger management classes at Boise State? She is here to testify. Do you want to tell this jury the truth?' Defense rests. State calls Ukwuachu's former girlfriend in Boise, Idaho, as its first rebuttal witness. She said he choked her and punched her in the head several times. Those assaults led to Ukwuachu being sent to anger management.

The jury found Ukwuachu, 22, guilty of sexual assault in an October 2013 incident involving a former Baylor soccer player. — Tommy Witherspoon (@TSpoonFeed) August 21, 2015

Ukwuachu is crying loudly as Judge Matt Johnson polls the jury about its verdict. — Tommy Witherspoon (@TSpoonFeed) August 21, 2015

Baylor responds with a vague statement:

Acts of sexual violence contradict every value Baylor University upholds as a caring Christian community. In recent years we have joined university efforts nationally to prevent campus violence against women and sexual assault, to actively support survivors of sexual assault with compassion and care, and to take action against perpetrators. We have established and fully staffed a Title IX office that employs a Title IX Coordinator and two full-time investigators. Maintaining a safe and caring community is central to Baylor's mission and at the heart of our commitment to our students, faculty and staff.

No one is impressed by the statement.

Among other reactions to the entire story, two Baylor players reference It's On Us, the White House campaign against campus sexual assault.

Some Waco media members respond to the point that it's curious nobody discovered any of this until right before the trial. From tweets by Paul Catalina, an ESPN radio host:

I dispute the notion that the Sam Ukwuachu case was covered up. We (the media) dropped the ball on digging deeper. It played out in court. I was at the trial all four days. Baylor Dept. of Judicial Affairs investigation was a key point, and looked as if it was very controversial. But Baylor was still going to have to let it play out in court, which it did, and there is now a verdict. Media would have dug deeper. If Baylor was never asked about a case, why would they just provide the info? Ukwuachu never played a down. Coaches wanted him back if cleared. Sam Ukwuachu was not cleared as you can all see tonight. I would dismiss any notion of a conspiracy. That being said ... The competency of the internal investigation by Baylor Dept. of Judicial affairs was a key factor IMO. Knowing what we know NOW, Baylor probably should have passed on bringing in Sam Ukwuachu. But a lot of teams would have done the same thing.

August 21, 2015: Briles denies knowledge of what really happened at Boise State.

Art Briles: "I talked with Chris Petersen personally. No mention of anything beyond Sam being depressed, needing to come home." — Max Olson (@max_olson) August 21, 2015

Briles: "It's unfortunate for everybody concerned. That's really about it. Our timeline was followed by what the standards were here." — Max Olson (@max_olson) August 21, 2015

Art Briles emphatically denied he was aware of Sam Ukwuachu's violence issues at Boise State, said "there's no truth" to that accusation. — Max Olson (@max_olson) August 21, 2015

Briles on taking transfers: "We're always going to make sure that a guy is worthy of that opportunity." — Max Olson (@max_olson) August 21, 2015

Here's the transcript of Briles denying knowledge of Ukwuachu's violent history. Important answer. pic.twitter.com/vLlCVJBYN3 — Max Olson (@max_olson) August 21, 2015

And Petersen has commented.

I don't really know what Petersen means by that.

Later that day:

The jury recommends that Sam Ukwuachu be sentenced to 8 years in prison but that the sentenced be probated. — Tommy Witherspoon (@TSpoonFeed) August 21, 2015

The judge sentenced Ukwuachu to felony probation for 10 years, placed him in the county jail for 180 days and 400 hours of community service — Tommy Witherspoon (@TSpoonFeed) August 21, 2015
