The FBI has released a new sketch of a second person of interest in the unsolved 2016 killing of college baseball star Calvin Riley.
Riley, 20 was gunned down in San Francisco on the night of August 6, 2016, while he was playing the video game, Pokemon Go, with a friend.
His loved ones said he was struck from behind. His friend heard the shot and saw the 20-year-old fall to the ground.
Riley was a rising star for the San Joaquin Delta College Mustangs, who dreamed of playing for the Red Sox. But his killing has remained a mystery for the past nine years.
Earlier this week, however, federal investigators revealed the new composite drawing in the hope that those responsible can finally be found. It shows a bearded man with glasses.
Riley's father, Sean Riley, paid tribute to the authorities and told KTVU that he hopes this represents a turning point in the investigation.

'They've done an outstanding job,' Riley said of the FBI. 'It's been a lot. I mean, it has been nine years.'
The family also posted a statement to social media, per Fox News, which read: 'There’s not a day, hour, minute or second that we don’t think about you and the great memories that you left us with.
'Calvin, we promise you that we will find this person and bring them to justice. Cal we love you and miss you so much. Until we all meet again!!!'
Both the killers and the motive have remained a mystery. The FBI is offering up to $25,000 as a reward for information that helps bring down those responsible.
Not long after the shooting, police released a sketch of one person they thought could be connected to the case. The man was reportedly driving a car - with a blonde woman aged between 20 and 30 - which was parked nearby.
According to KTVU, a family friend previously said Riley and his friend had noticed someone watching from the top of the hill above them.
Another person was seen recording the crime scene and the new sketch shows a bald man with a beard and glasses. Police also identified a couple of suspicious cars - a 2015 white Hyundai Sonata and a dark Audi A3 - that arrived together and left together after the killing.
It's not believed Riley was involved in any confrontation or robbery before being shot. Neither his phone nor his wallet was touched. 'This has ripped my family apart,' Sean Riley said at the time. 'I miss my family. I miss him. I miss it all.'
