Police have revealed that robbery may have been the motive in the homicide of a Penn State student in Philadelphia over the weekend.

Philadelphia Police Department Cpt. Benjamin Naish said there are clues that Tyrone Myers, 22, had an unknown amount of cash stolen from him either before or after he was shot four times in the back.

Investigators found Myers' pockets turned inside out, and a broken cell phone and some money were next to him on the ground, Naish said.

Funeral services for Myers will be held in North Philadelphia's Bright Hope Baptist Church tomorrow. Viewing is from 9 to 10 a.m., with the service following.

A memorial service is also scheduled for 7 p.m. Monday at the Pasquerilla Spiritual Center.

Myers was shot after getting out of his car near his aunt's house around 4:30 a.m. Saturday after he was coming back from a bar.

Police said they are continuing the investigation but have no suspects at this time.

Myers was home to attend the funeral for another aunt, who had died after an illness. Myers was a senior who was scheduled to graduate in August with a biobehavioral health degree.

Myers' sister Twande Myers, 24, said her brother was the hardest working person she knew and would have been the only one in her family to graduate college.

"He was focused and never took anything for granted," she said.

Adrienne Carducci (senior-biology) said she saw Myers, her good friend, briefly just days before the incident when he told her to call him and they would hang out.

"I fell asleep and didn't get up in time to see him," she said. "I'm probably going to regret that the rest of my life."

She said she and Myers kept each other grounded and pushed each other because of their difficult majors.

"We had plans of hanging together all summer because him and I were going to be the only two up here at Penn State," she said.

She said one of the hardest parts about Myers' death is that he will never be able to complete his degree, get a successful job and truly make his grandmother, whom he lived with, proud.

"But he did what he had to do on earth, and it was his time to go," Carducci said. "I feel a little bit more at ease at night knowing that he's looking down on me."
