Back at Wright & Co. Law Offices, Ema apologizes for what Lana said, and reveals that the the night Marshall's brother was murdered, Joe Darke tried to kill her. Neil Marshall tried to save her, but lost the battle to the death, and so Ema became a witness in the case.
Talk to Ema:
Lana was a detective? Move to the Detention Center to talk to her.
Talk to Lana:
Phoenix doesn't believe it — that all the people involved in the current trial were also involved in SL-9 seems a little too convenient. Although the case was supposedly solved two years ago, there are still people like Jake Marshall that aren't satisfied either. Since Neil's murder took place there, you should probably go check the Chief's Office for more information. Move to the Criminal Affairs Dept.
You find nothing interesting here, and you won't find Gumshoe. Move to the Police Dept. Entrance.
You'll find Marshall. Talk to him.
Marshall is done with his story, and tells you that although Edgeworth presented the evidence, it was Damon Gant who falsified it and planned the whole thing. When he leaves, move back to the Criminal Affairs Dept.
Still nothing there, but the Chief Detective tells you everyone is in the conference room trying to deal with all the chaos of the last few days. You'll also learn where Gant's Office is. Move to the Chief's Office.
After a few minutes of sight-seeing, you'll meet Gant, who puts a piece of paper in his desk after he comes in. Gant shows you a picture hanging on his wall. It's Lana, Neil, and Gant. Something is weird in the picture, but you can't put your finger on it. The Gant Team Picture will be added to the Court Record. Gant then decides to lock up the room, and takes you with him. He is kicking you out? Against your request to investigate? Move to the Criminal Affairs Dept.
You meet Gumshoe, who was serving coffee in the meeting, saying that Edgeworth is now "under fire" since the rumors were true. Talk to Gumshoe.
Maybe presenting the Switchblade Knife would jog his memory. Talk to him after he recalls. After you present the Switchblade Knife, go back and talk to him to get some answers.
Gumshoe admits that the whole scenario was conjecture, since they never found a shred of evidence. There was a good chance he would've gotten away with it, except for the incident at the Chief's Office, where he left a witness to the murder of Neil Marshall.
You ask Gumshoe to let you into the Chief's Office, but he can't, as letting a civilian in there would result in him losing his job. Although any detective's ID card can get you into the office, the data on Goodman's ID was deleted the day he died, so you need to find something to get Gumshoe to help you. Move to the Underground Parking Lot.
Everyone seems to be investigating the other crime scene. You've proven that there wasn't a murder there, but you've also made Lana seem even more guilty. Move to the High Prosecutor's Office.
You'll see Edgeworth, who throws whatever he was writing down on the ground upon seeing you come in. Talk to Edgeworth:
Present Edgeworth with the Gant Team Picture. Ema notices that Neil's trophy is different than Edgeworth's.
An arms merchant presented the emperor a halberd that could penetrate any shield or armor, and a shield that could withstand any weapon. The emperor then spotted what would be called a contradiction, and the Chinese word for contradiction was born. Hence the broken knife and chipped shield in the Prosecutor Trophy symbolize the merchant's items.
But there is only a shield on Edgeworth's trophy. The halberd part was abolished two years ago by Damon Gant, who Edgeworth says you should talk to about it. The Prosecutor Trophy will be updated in the Court Record.
Examine the piece of paper under Edgeworth's desk. It's a letter of… resignation? Edgeworth feels as if something has died inside him. He can't forgive himself for the path on which he walked. The Letter of Resignation will be added to the Court Record.
Move to the Underground Parking Lot.
You'll meet Angel, who is still harping on witnessing Lana stab Goodman. Talk to Angel:
Everyone like Lana and wanted to be like her because she hated anything crooked and watched out for the other detectives. She felt especially bad for Jake, and when his brother was killed she felt like she'd lost a brother herself. If wasn't for her, Jake might not have gotten over the shock of the murder. But something happened to make her change and become so cold.
Finally, you are getting closer to the bottom of this. Move to the Criminal Affairs Dept.
You'll meet Gumshoe, who still refuses to let you into the office. You need something to change his mind.
Present Edgeworth's Letter of Resignation to Gumshoe, who'll be shocked at seeing this. Edgeworth trusted detectives to give him sound evidence, but was betrayed. Gumshoe feels very sorry and would do anything for Edgeworth now. He then makes up his mind and gives you his ID card. Gumshoe's ID will be added to the Court Record. Move to the Chief's Office.
You arrived at the Office… followed by Gumshoe, who was worried something might go wrong. Why did he give you his ID card anyway? Gumshoe's ID will be removed from the Court Record. Talk to Gumshoe.
Examine the safe behind Gant's desk on the right side of the room. It looks like you need a code to open it. You have a choice, choose "Input number". At the bottom of the screen, you'll find a keypad like you would find on a phone. Type in "7777777" and the safe will open.
7777777? That's the ID number of the executive that entered the Evidence Room on the day of the crime! Gumshoe says this is Gant's number. No time for chat though, examine the safe again and you'll find a broken piece of jar, and a piece of leather cloth with a handprint on it. Gumshoe wants to know if there is a connection between the two pieces and the case before he'll let you take them.
Start with the shard. Present the Unstable Jar to Gumshoe. Remember yesterday, you found pieces like this and put it together. Gumshoe then notices the possible connection. You have a choice, choose "Assemble fragments", and you'll put the final piece in there.
It fits! Gant was obviously hiding the fragment in there. He was hiding valuable evidence in there! But why? Gumshoe then points out something. There's blood on it! Could this be part of the reason? The Unstable Jar is updated in the Court Record.
Now for the cloth. Present the Fingerprinting Set. You choose a finger you want to test: the middle fingerprint in this instance. Once you start, sprinkle all around the touch screen and blow. After the fingerprint is clear, you get to choose its owner. It's Ema Skye's! This seems to be a very grim piece of evidence, but you can't tell Ema about this for now. The Strip of Cloth will be added to the Court Record.
Examine Gant's desk. The first time you came in here, he hid something he was reading from you. It's an evidence list saying, "SL-9 Incident!". Remember, Edgeworth said his evidence list for SL-9 is twice as short as an average one. This must be the other half of the list; it was ripped in half! The Evidence List will be added to the Court Record. If you check the Evidence List and rotate it to show the back, you can examine it to find a crude drawing of what looks like a figure about to stab another person. Didn't Ema say she drew what happened that night? At any rate, it's best not to disturb her, so you keep it to yourself.
Gant is obviously hiding something! Speaking of Gant, uh-oh! He somehow sneaked in to see you three in his room. He has you and Gumshoe leave, but wants Ema to stay for questioning. You automatically go to the Detention Center.
What Lana has told you over the past few days is nothing useful. Talk to Lana:
Present to her the Evidence List. Lana finally gives in, and tells you that she does follow Gant's orders and three days ago she got orders to concerning Detective Goodman.
If that is true, then Lana wasn't the one who killed Goodman! When Lana opened Edgeworth's trunk, she found Darke's knife plunged inside him, so she took the knife out, and plunged Edgeworth's Knife inside instead. That's when Angel saw her. Why did she have to hide the Switchblade Knife so badly?
When she got the orders from Gant, the first thing Lana did was call Marshall, thinking she could trust him to help her hide the body. He had plans of his own to keep the case from dying, and after Lana's phone call, he resolved to use the stolen ID card to get the evidence from the Evidence Room.
Lana is finished talking with you, and doesn't want you to pursue this further in court. It looks like you're done for today. Tomorrow you'll have to prove the mystery behind Goodman's murder, the SL-9 Incident, and Lana's secret.
