A man wanted in a Plano killing died Monday. He died after a high speed chase on Interstate 35. The chase shut down the highway for hours in Denton County.

The case started the night before. Police say it ended with gunfire. Then came a burning car. Then a long standoff on the side of the highway.

Police say a woman was shot and killed late Sunday night. It happened inside a home in Plano. The home sits in the 1100 block of Lakestream Drive, near Parker Road. Officers say she knew the man who shot her. Other family members were inside the home at the time. None of them were hurt. Plano police have not released the woman's name yet. They are waiting to tell her family first.

The next morning, a Texas state trooper spotted the man police wanted. He was driving north on I-35. This was in northern Denton County. The trooper tried to pull him over. Instead, police say the man opened fire at the trooper.

The trooper was not hit. But the man sped off. A chase started on northbound I-35. It began around 10 a.m. Monday.

The chase headed north toward the Cooke County line. It passed through the small town of Valley View. Near Chisam Road, the man crashed. That spot sits between exits 481 and 482.

His car caught fire. A standoff followed right there on the shoulder of the highway. Police say the man was confirmed dead at the scene. Officers have not said exactly how he died.

No officers were seriously hurt in the chase. None were seriously hurt in the standoff either.

The chase and the crash shut down both sides of I-35. The highway stayed closed for hours. Traffic backed up close to five miles. Drivers sat and waited. Police needed time to work the scene. The highway reopened by early afternoon.

Three police agencies worked together on this case. Plano police were chasing the man for the Sunday night killing. Valley View police and Texas state troopers spotted him on the highway. They were the ones who tried to stop him. A Plano police spokesperson, Jerry Minton, confirmed the man was wanted in the shooting.

Cases that cross city lines show how fast things can turn deadly. A routine traffic stop became a chase in seconds. The man was driving through Denton County. That is far from where the shooting happened in Plano. A trooper who did not know about the Plano case still ended up in the middle of it. Shots were fired within moments.

High speed chases put everyday drivers at risk too. Innocent people sat stuck in traffic for miles. They waited while police worked to make the highway safe again. No bystanders got hurt this time. Chases like this do not always end that way.

As of this report, police have not released the man's name or his age. They have also not released the woman's identity. Plano police said they plan to share more details soon.

A medical examiner has to confirm who both people are. That happens before police can release their names to the public. This step can take some time. It is standard procedure in any case where someone dies.

Police have not named either person as of this report. Their names may come out in the days ahead once police finish their work and notify the families.

Everyone is presumed innocent until proved otherwise.
