Prosecutors: Dale Smith Jr. bought flight days before arrest

New here at five tonight. We're learning police arrested the man accused of murdering Michelle Parker just a few days before he was sent to travel out of the country. Welcome in at five. I'm Jack Royer and I'm Luann Sorrell. Dale Smith Jr. has been locked up in the Orange County Jail for the past week. Fox 35's Manny Martinez is live there tonight. So many prosecutors also say the suspect's son went to police to ask if his father was still a suspect in this case. And Luann, prosecutors say that visit was earlier this month, about two weeks before Dale Smith Jr. was arrested. We're learning all of this from a court filing today, where prosecutors are asking the judge to keep the affidavit, the paperwork that explains how police zeroed in on Dale Smith Jr., sealed out of the public until next Monday. Prosecutors say October 2nd, Dale Smith Jr.'s son, one of the twins he shared with a woman he's accused of killing, went to police to ask about the status of the case. like do they have leads on the location of his mother's body and whether his father was still a suspect. The state attorney's office says Tuesday of last week, cops found out Smith Jr. was planning to fly to Colombia, the country in South America. The flight out was scheduled for the 16th with what prosecutors say was an easily cancelable return trip on the 19th. Police arrested Smith last Wednesday on the 14th. Prosecutors say police waited to do two out-of-state interviews with witnesses until after they arrested Smith because they didn't want him to flee. His attorney says there's nothing wrong with a weekend trip abroad because he says it's a trip his client has made 18 times in the last six years. I've got his passport here with stamps. He goes there usually on a Friday, comes back on a Sunday. He's romantically involved with somebody in Columbia. So he didn't know this arrest was coming. He didn't know the investigation was still hot. Smith is charged in the murder of his ex-fiancée, Michelle Parker. Police say he was the last person to see her that night in November of 2011 when she was dropping off the twins at his house. It was the same day the couple appeared on a pre-taped episode of the People's Court, arguing over a $5,000 engagement ring. Smith's attorney, along with several local news outlets, are pushing for the public release of the full investigative paperwork. They arrested him. They do a press conference. They have all these authorities talking about all this new evidence, but they won't show it. They won't show it to the media. They won't show it to the public. For 15 years, they've been saying my client is the sole suspect, but they haven't shown one shred of evidence. His attorney, very obviously passionate about this. Prosecutors say they're going to let the court filings do the talking for now. Coming up next hour at six, how Smith's attorney says police turned what was supposed to be his son asking them questions for an update on the case into an interrogation. We're live in Orange County.
