Lockport, NY (WKBW) - New details were revealed about the criminal past of the man at the center of Wednesday's deadly standoff in Niagara County.
Tucker is at least a two time felon. At one point he was also a suspect in the brutal murder of a 13-year-old Buffalo girl.
Wednesday morning, Sheriff's deputies stormed the neighborhood where Tucker and his wife, Leanne, lived. Deputies say Tucker shot his wife in the face before killing himself. The entire time, their three-year-old child was inside. Authorities had to coax the child out of a window.
This shooting comes just a year and a half after Tucker finished parole. He confessed to shooting Jenipher Behm in the head in 1998 in Lockport.
After a plea deal in May of 1999, Tucker told Eyewitness News "it was 100-percent an accident" and that he "had no choice" but to take the plea.
Prosecutors originally charged Behm with murder, two counts of assault and criminal possession of a firearm.
However, when the sole witness, and Tucker's best friend at the time, would not cooperate, authorities made a plea offer for attempted assault.
After Tucker proclaimed the shooting was an accident in 1999, Behm's aunt, Gleneda Holmes, told Eyewitness News "She was shot intentionally. She was a tall girl and shot in the head. They said it was execution style."
Behm's cousin, Delores Fiddell, added "Why is it square through the head? He had to put it there."
Tucker served six of a seven year sentence in Gouverneur State Prison. He was released in August of 2005, but then had to return for one year after violating the conditions of his parole.
In 1998, investigators took another look at the case of the brutal 1984 Buffalo murder of 13-year-old Michelle Kasperek.
The State Supreme Court ordered Tucker give blood and hair samples. Prosecutors say Tucker was at the same party as Michelle the night she was killed. They add a cross, carved into her cheek was similar to a tattoo that Tucker had.
After the order was issued, his attorney at the time, Joel Daniels, told Eyewitness News Tucker had given DNA evidence back in 1984. However, prosecutors wanted to re-examine the case because of better technology in DNA testing.
No one was ever charged and Kasperek's murder remains unsolved.
The ATF is investigating where Tucker got the gun used to shoot his wife and himself.
Leanne Tucker is in ECMC in critical condition.
