PALM BEACH COUNTY, Fla. - While Albert Lambert's three daughters went before the world begging for their mom to come back home -- law enforcement was already suspicious of their dad.
"He clearly knew he was the main suspect. he planned on this crime and I think he was very surprised how quickly law enforcement was tracking him and linking him," said Palm Beach County State Attorney Dave Aronberg.
He says Lambert thought he was going to outsmart them by using his youngest daughter's car to move Kim's body.
NewsChannel 5 has learned there was gunpowder found on the steering wheel.
It's the same steering wheel Lindsey's daughter would hold as she drove to school the next morning -- having no idea her dad used her car.
"I think it is evidence of premeditation and he thought about this in advance," the state attorney said.
Aronberg says they waited until Sunday to try to make an arrest because they wanted to build their case strong enough that he wouldn't have a chance of getting bond. "Even if you have probable cause, you need a higher standard, a higher form of evidence to keep the person behind bars with no bond. That was key. If we were going to make an arrest we wanted to make an arrest with no bond," Aronberg says.
that arrest never happened because Lambert was found dead at his sister's home in Miami.
Lambert's attorney says he had heart problems -- and may not have committed suicide. But Aronberg says, "I don't believe it was an accidental overdose."
He says the most dangerous time in a relationship is when it ends -- and that Lambert knew he was losing control of his ex-wife.
At a court hearing Lindsey's lawyer attempted to make the case that the former married couple had a rough relationship. A text message Lambert sent Lindsey before her disappearance said,
"Look at your pathetic self first. You are a welfare mother just like the ones you always made fun of."
Lambert's response to the text was, "Those are words I placed in the text when I was upset after she insinuated I wasn't going to take care of my kids."
Now he's left daughters Sarah, Savannah, and Sofia with no parents.
"We're about doing justice. In this case there is justice in this world and justice afterwards. I think ultimately he will find justice," Aronberg said.
