It was the surveillance video police say led them to 21-year-old Terrell Gibson, arresting him Thursday morning in West Baltimore for the murder of Chief T.J. Smith’s brother Dion.
"He was arrested relatively without incident,” Commissioner Kevin Davis said. “He did have someone in the house who was trying to conceal his whereabouts, but we were able to otherwise take him into custody without incident."
Police were not able to recover the gun they say he used to kill 24-year-old Dion Smith.
Gibson is no stranger to police.
They say he was charged in 2015 in relation to a stabbing on the Light Rail in March of that year.
Then, Baltimore Police released pictures of him and five other suspects.
He was arrested, did some time and then released from probation this past December.
Police now say it is that same man on this video they released Monday, a key piece of evidence linking him to the murder of Chief T. J. Smith's brother.
"We know we've got the right guy and thankfully he is off the streets and he won't live to hopefully harm anybody else like he harmed Dion and the Smith family," Davis said.
But the arrest of Gibson closes just one of several recent homicide cases that pushes the total to 180, a 26 percent increase over this time last year.
A few weeks ago, Baltimore Police deployed a 12-hour shift schedule after a similar spate in violence and saw some success.
It is an option that is again on the table as the department looks to use every sworn member to patrol the streets.
"We want to strategically put them out, we want to strategically do roll calls in specific areas and specific neighborhoods and we need to be able to sustain an enforcement effort,’ Deputy Commissioner Dean Palmere said. “An omnipresence of such in the field for the remainder of the summer."
In addition to announcing the arrest of Terrell Gibson, police also said they have a suspect in the 4th of July stabbing at Howard and Fayette Streets.
There is a warrant out for his arrest and police say they should release his name soon.
