Updated after the jump: Christopher Earl Glass was a star high-school basketball player, and may have been traumatized from his grandmother's death six months prior.

The Palmdale teen who allegedly abducted his 5-month-old baby and led sheriff's deputies on a three-minute chase around 3:30 p.m. today has been declared dead, according to the L.A. County Sheriff's Department.

Deputies followed 17-year old Christopher Earl Glass' SUV until it crashed at the Palmdale Metrolink Station. At that point, they saw him take out a weapon and stab the baby to death — before running into a nearby house on the 500 block of East Avenue P-14.

One deputy decided to follow Glass into the building…

… and, after a confrontation that is still under investigation, fatally shot the teen just minutes after he murdered his own baby boy.

According to the original ABC7 report, the baby was declared dead after being transported to a nearby hospital.

An Amber Alert had been issued around 2 p.m., when Glass left the baby's mother's house after an argument — with their child in tow. From the department's own report, just now released:

Palmdale Sheriff's Station deputies responded to a report of a child abduction in Palmdale at about 11:00AM, Tuesday.

They were told that a 17-year suspect had kidnapped his 5-month old baby son from a person who was taking care of the baby, and drove away.

As deputies investigated the kidnapping, the suspect phoned the mother of the baby and threatened to harm him.

Then, after a few hours of manhunting, at about 3:30 p.m.:

Los Angeles County Sheriff's deputies who were searching for the suspect and baby saw the suspect driving in the area and began to follow him. The deputies saw the suspect motion in a manner that appeared as though he was stabbing the baby as he drove his car. Attempting to get him to stop, deputies went in pursuit of the suspect's vehicle. After about 2-3 minutes, the suspect was involved in a single-vehicle collision, striking a building.

The suspect got out of the car and ran, and deputies chased him on foot.

Other deputies ran to the suspect's car, picked up the baby, and raced him to the hospital in their radio car. Unfortunately, the baby was pronounced dead at the hospital.

Deputies chased the suspect and saw him attempting to break into the home of a family the suspect didn't know, and a Deputy-Involved Shooting occurred. The suspect was able to break into the home, with deputies chasing after him. A second Deputy-Involved Shooting occurred inside the home.

Update: Fox11 reported last night that Glass was a star on his Highland High School basketball team. Some shocked friends and family have been interviewed by various news stations, remembering stuff like “He was very excited. He was like any other dad, he was just happy to have a baby” and “He loved that baby. He would be holding the baby, feeding him, changing his diaper. I mean, he was a great dad. That's why it's a shock.”

However, Glass' relatives have also indicated they noticed a change in the boy after he discovered his grandmother dead six months ago, and allegedly came away quite traumatized.

One witness to the Metrolink Station crash told reporters: “All I saw was this car come flying and it hit the column, so I ran. And this guy jumps out with a knife in his hand, so I ran away just in case so he doesn't get me.”

The baby's name was Chris Jr., or CJ.

One LA Weekly commenter, Dsweetbabe1, says:

“This is very sad, I don't know why he did this. He was very nice and a quiet person who I never thought would do this. It's a shock to me and even though he did something like this he will be missed by those who knew him…”

Here's the KTLA video, including photos of Glass' 5-month-old:
