Jurors shown bloodstained carpet and surveillance video in Naresh Bhatt trial

New evidence presented today in Naresh Bhat's murder trial. He's the man accused of killing his wife, Mamta, back in 2024. The jurors seeing a blood-stained carpet from the family's home and videos from what prosecutors say was a key trip to Walmart. Fox 5's Stephanie Ramirez live outside the court with the very latest tonight, Steph. And guys, closer to the end of trial today is when we saw some of that surveillance video. Take a look at this from Walmart showing the defendant, Naresh Bhat, purchasing what investigators have hinted could be a possible murder weapon. Bhat purchasing three knives on July 30th of 2024. It was a big day in court, literally, in other moments. And that came when a large, some 8-by-10-foot piece of carpet was brought into the courtroom, rolled out by Prince William County Police Investigator Joseph Restino with the help of prosecutors. He told the court he cut this piece out of the defendant's bedroom. And we couldn't really see it from the gallery. But in court, evidence photos were shown of the suspected bloodstain that Rustino says he found underneath the carpet where forensics previously had a Blue Star hit. The carpet brought in today is the same Blue Star evidence we showed lit up yesterday, actually, when the Blue Star agent detects possible traces of blood. Rustino says back at their office, he cut a sample to send to a lab for DNA testing and that he also pre-swabbed it, the swab showing in pink, meaning positive for blood. Investigators also Blue-Starred and photographed other parts of the home. Now, we did blur out some of the reddish-brown stain in the photo. In the master bath, Rustino told the jury he pulled out the defendant's bathtub as part of evidence collection and found a stain where the bottom of the tub would sit, believing a large volume of blood seeped through the tub caulking. The defense challenged some of this. you have this positive reaction but you can't know from the reaction how that substance ended up where it ended up right no you don't know when it got there i do not you don't know why it's there i do not the thing about any scientific method is that even though it has some limitations it doesn't diminish its scientific value can BlueStar detect blood that someone has attempted to clean. Yes, BlueStar is, that's one of the main uses for it at crime scenes is to locate blood that's not visible to the naked eye. Now guys, that last person you heard from there was brought in as a BlueStar expert. She testified that BlueStar does not confirm blood, but it is used as a law enforcement tool. The investigator we heard from earlier in the day, he testified that he wouldn't expect to see that type of positive reaction or as much of a positive reaction in the defendant's bedroom, guys.
