KUSA - The mother of a 16-year-old who was shot by Denver police Monday says her son was just released from a psychiatric ward a few weeks ago.

Janine Pinto says her son Cody Seastone is bipolar, was on a new medication and she thought he was getting better. That is, until he had a meltdown on Monday. She said he took a knife and slashed walls and a screen door at the home he lived in with his grandmother.

"I said, 'Cody please knock it off. The cops are going to come,'" Pinto said. "And he goes 'I don't care.'"

"When [police] pulled up, he stood up and he had the knives in his hand and [police] came out and drew their weapon."

Christine DeLuz, Seastone's grandmother said police asked her grandson to drop the knives.

"They did that several times and he was yelling back at them," DeLuz said. "He took one hand and [Seastone] raised the knife and [police] started shooting."

"I freaked," Pinto said. "Everybody freaked. And [there was] just disbelief that they shot him."

"He did not move menacingly to the police. I think he could have been shot with a Taser - maybe a rubber bullet - or bean bag or something," DeLuz stated. "He was only 16. I don't think guns were necessary."

DeLuz, who is disabled, says Denver police treated her well after the incident.

"They were very, very kind [and] very accommodating," DeLuz stated. "They really went out of their way to be kind to me."

Pinto said she was allowed to see her son in the hospital once after the shooting.

"He was aware I was there," Pinto said. "He did wake up for a split second and he was struggling against the drugs. He started to cry, but he couldn't answer cause there was a tube in his throat and his leg was in a cast."

"I don't know where to go or what to do from here," Pinto said. "It's very difficult."

"I hope he gets help to be able to get himself straight," DeLuz said.

Police originally said Seastone was 17, but his family says he won't be 17 until this summer.

He is in critical, but stable condition at a local hospital.

The officers involved are on administrative leave, which is standard procedure after an officer-involved shooting.
