A second Holts Summit teenager has been charged in a 2019 murder in Cole County.

Grant Deppe, 17, was charged Tuesday with second-degree murder, armed criminal action and tampering with physical evidence in connection with the shooting death of Marquise Conley, 18, on Oct. 31, 2019.

In November, Cole County prosecutors charged Devin Schrimpf, 17, with first-degree murder and armed criminal action for Conley's death.

At the time of Schrimpf's arrest, police said another juvenile male had been taken into custody in connection with this crime. Cole County Prosecutor Locke Thompson confirmed this was Deppe, who was certified as an adult Monday to face these charges.

Deppe remains in custody with no bond, court records show. His case was assigned to Cole County Associate Circuit Judge Cotton Walker, but no court date was shown as of Tuesday.

Schrimpf also is in custody without bond and no court date scheduled.

Authorities allege Deppe acted with Schrimpf to cause Conley's death and that Deppe concealed a firearm used in the crime.

Officers were called at 3:19 a.m. Oct. 31 to a residence in the 1900 block of Rolling Hills Drive for a reported weapons offense, according to a Jefferson City Police Department probable cause statement. They found Conley dead in a back bedroom as a result of multiple gunshot wounds.

A witness stated Schrimpf had placed multiple calls to the residence prior to the shooting. Schrimpf allegedly had said he would "pull up" and "shoot" the place up.

A second witness told officers Schrimpf had gone to the Rolling Hills address during the day Oct. 30 and became angry when he learned another man was in the house. The witness said Schrimpf had to be forced out of the home. After leaving, he allegedly called the witness saying he would "kill everybody over there; I'm shooting the place up."

This second witness was admitted to St. Mary's Hospital about two hours prior to the shooting. Hospital video reportedly showed Schrimpf arriving at the hospital a few minutes after the shooting was reported. When asked what Schrimpf had talked about at this time, the witness stated Schrimpf had said, "It's just me and you; it's always going to be me and you."

Schrimpf allegedly admitted to detectives he had made a phone call to the first witness and had visited the home earlier in the day and another man was there. Detectives reported Schrimpf "provided inconsistent information and was deceptive during the interview."
